Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
An embodiment of the present application provides an information determining method, which is applied to an electronic device and shown in fig. 1, and the method includes the following steps:
In the embodiment of the application, the video information to be displayed can be a video needing to be played; in a feasible implementation manner, the video information to be displayed may include video information to be played, or video information of the other party when a video call is performed, and the like. The image of the video information to be displayed may refer to an image included in the video information to be displayed; it should be noted that the image of the video information to be displayed may be obtained by obtaining the image of each frame of the video information to be displayed; or, the images of the video information to be displayed may be obtained by obtaining the images of different frames of the video information to be displayed at intervals.
In an embodiment of the present application, the target information of the background image may refer to attribute information of the background image of the image in the video information to be presented, or information related to the content of the background image. The target information may be obtained by analyzing a background image of an image of the video information to be displayed or contents of the background image. The target background audio may be determined directly based on the target information, or may be obtained by processing the background audio of the video information to be displayed based on the target information. It should be noted that, if the target background audio is determined directly based on the target information, the determined target background audio is matched with the target information.
And 103, obtaining target video information based on the target background audio and the video information to be displayed, and displaying the target video information.
The video information to be displayed can be processed based on the target background audio, so that target video information with the background audio as the target background audio is obtained; it should be noted that the target video information may be obtained by combining the target background audio with the video information to be displayed. In other embodiments of the application, the obtained target video information can be directly played on a display screen of the electronic device, or the video information of the opposite side in the video call is directly replaced by the target video information; however, the user does not intuitively feel that the currently played video information is obviously changed, and only the background audio of the currently played video information is heard to be changed into the target background audio, so that the user can see the video information with the background audio matched with the background image, and can obtain various background audios with different effects.
The information determining method provided by the embodiment of the application can acquire the image of the video information to be displayed, determine the target information of the background image of the video information to be displayed, determine the target background audio corresponding to the background image based on the target information, and then obtain the target video information based on the target background audio and the video information to be displayed and display the target video information.
Based on the foregoing embodiments, an embodiment of the present application provides an information determining method, which is shown in fig. 2 and includes the following steps:
In the embodiment of the present application, after step 201, steps 202 to 203, or steps 204 to 205, or steps 206 to 207 may be optionally performed.
Wherein the target information includes a degree of blur.
In the embodiment of the application, the blurring degree of the background image can be determined based on the blurring degree of the background image which is input by a user in advance and aims at the image of the video information to be displayed; it should be noted that the electronic device may process the background image of the video information to be displayed based on the value input by the user by using a fuzzy algorithm in the image processing algorithm, so as to obtain an image in which the background image is fuzzy; the blurring algorithm may include gaussian blurring (gaussian blur) or mean blur (mean blur), among others. Of course, the degree of blur of the background image may also be determined by analyzing the background image with an image processing algorithm. Wherein, the degree of blur of the background image can represent the degree of blur of the background image.
And 203, the electronic equipment performs noise reduction processing on the background audio of the video information to be displayed based on the fuzzy degree of the background image to obtain the target background audio.
In the embodiment of the application, the electronic device may analyze the audio in the video information to be displayed, determine the background audio therein, and then perform noise reduction processing on the obtained background audio; that is, if the video information to be presented is conference video information, it is necessary to distinguish the voice of the speaker from the voice of the background. In one possible implementation, the electronic device may employ Speech enhancement (Speech enhancement) and Speech separation (Speech separation) techniques to distinguish the speaker's Speech from the background's sound; also, the most commonly used is the clustering algorithm (Deep clustering).
In other embodiments of the present application, the electronic device may perform noise reduction processing on the separated background audio to match with the degree of blur of the background image, so as to obtain a target background audio matching the background audio and the background image. It should be noted that the degree of blur of a general image may be set to a value between 0% and 100%; at this time, the electronic device may determine a value of the degree of noise suppression to match with based on the value of the degree of blur of the background image, and then perform the degree of noise reduction between 0% and 100% on the background audio. In one possible implementation, the value of the degree of noise reduction for the background audio may be considered the same as the value of the degree of blur for the background image. In addition, in the embodiment of the application, the background audio in the separated video to be displayed is subjected to a certain degree of noise reduction processing based on the blurring degree of the background image, instead of directly eliminating the background noise as in the relative technology, so that the background audio and the background image are matched, and meanwhile, useful background sound is prevented from being eliminated.
And step 204, classifying the background images by the electronic equipment to obtain the types of the background images.
Wherein the target information includes a category of the background image.
In the embodiment of the application, the electronic device may also determine the target background audio based on the category of the background image; that is to say, the electronic device may classify the background images by using an image classification technique to obtain different types of background images, so as to determine the type of the background image in the video information to be displayed that is currently to be processed; the category of the background image can represent what kind of image the background image is; in one possible implementation, the categories of the background image may include landscape images, people images, animal images, object images, and the like.
The electronic device may use an Image processing algorithm to classify (Image Classification) the background Image to obtain the category of the background Image.
It should be noted that the electronic device may directly acquire or generate the target background audio matching the category of the background image. In a possible implementation manner, if it is determined that the category of the background image is an ocean landscape image, the electronic device may obtain or generate a target background audio (for example, the sound of ocean waves, etc.) matching the ocean from the audio database; alternatively, if it is determined that the type of the background image is an office portrait image, the electronic device may obtain or generate a target background audio (e.g., a sound of a whisper discussion or a sound of hitting a keyboard) matching the office screen from the audio database.
And step 206, the electronic equipment performs image recognition on the background image to obtain scene information in the image content of the background image.
Wherein the target information comprises scene information in the image content.
In the embodiment of the application, the electronic device can perform image recognition on the background image by adopting an image recognition algorithm, so as to obtain the image content of the background image; then, the scene classification technology may be used to analyze the image content of the background image to obtain the scene information included in the image content. It should be noted that the scene information may refer to a scene currently indicated by the image content of the background image. In one possible implementation, the scene information may include an office scene, a marine scene, and the like.
It should be noted that the electronic device may directly acquire or generate the target background audio matched with the scene information in the background image. In a possible implementation manner, if it is determined that the scene information in the image content of the background image is an ocean scene, the electronic device may obtain or generate a sound related to the sea from the audio database as the target background audio (for example, the target background audio may be a sound of a gull); alternatively, if it is determined that the scene information in the image content of the background image is an office scene, the electronic device may obtain or generate office-related sound from the audio database as the target background audio (for example, the target background audio may be a sound of a colleague discussing work or a sound of hitting a keyboard).
In other embodiments of the present application, the determining the target background audio in steps 205 and 207 may be implemented by:
a1, the electronic device obtains the target background audio from the audio database.
The target background audio in step 205 and step 207 may be directly obtained by the electronic device from an audio database in which various audio information is stored in advance.
Or a2, the electronic equipment acquires the audio elements from the audio database and generates the target background audio based on the audio elements.
The target background audio in step 205 and step 207 may also be generated by the electronic device in real time or in advance; that is, the electronic device may obtain audio elements related to the target background audio from the audio database in real time or in advance, and then generate the target background audio using the obtained audio elements.
It should be noted that, after step 203, step 205 and step 207, steps 208 to 209 may be performed;
and step 208, the electronic equipment replaces the background audio of the video information to be displayed with the target background audio to obtain the target video information.
In the embodiment of the application, the electronic device can directly replace the background audio in the video information to be displayed by using the determined target background audio, so as to obtain the target video information. Meanwhile, the electronic equipment can play the obtained target video information. It should be noted that the target video information may be generated before the video information to be displayed is played, or may be generated after the video information to be displayed is played; in a feasible implementation manner, if the video information to be displayed includes a video conference in a video call, the target video information may be generated during the start of the video conference or may be generated after the start of the video conference. However, no matter when the target video information is generated, the whole process of generating and displaying the target video information of the information determination method provided by the application has no obvious perception for users, and the normal playing of the target video information and the video information to be displayed is not influenced.
And step 209, the electronic equipment displays the target video information.
Based on the foregoing embodiments, in other embodiments of the present application, the method may further include the following steps:
step 210, the electronic device obtains configuration information for the video information to be displayed, and determines whether the background image is a virtual background image based on the configuration information.
In the embodiment of the application, the configuration information may be some configuration parameters set by a user for the video information to be displayed; the configuration information may include configuration parameters of a function of whether the virtual background image is used or not for the video information to be presented; if the configuration parameter representation enables the function, the background image in the video information to be displayed is a virtual background image; if the configuration parameter indicates that the function is disabled, the background image in the video information to be displayed is not a virtual background image.
It should be noted that, the user may set the function of enabling or disabling the configuration parameters corresponding to the virtual background image according to the needs of the user or the needs of the actual application scene. Of course, if the video information to be presented is conference video information, the user may set the function of enabling or disabling the configuration parameters corresponding to the virtual background image according to the object of the video.
And step 211, the electronic equipment controls to play the target audio of the target video information based on the determination result.
In the embodiment of the application, the electronic device can control what audio information is correspondingly played when the target video information is displayed based on whether the background image is a virtual background image; that is, the electronic device may control whether the target background audio is played.
In step 211, the electronic device controls to play the target audio of the target video information based on the determination result, which may be implemented by:
and step 211a, the electronic device controls to play the audio of the speaking object of the target video information under the condition that the background image is determined to be the virtual background image.
In the embodiment of the present application, the video information to be displayed includes a video conference for explanation: if the function corresponding to the configuration parameter of the virtual background image is determined to be started, the background image in the video information to be displayed and the target video information is the virtual background image at the moment, the target background audio matched with the background image does not need to be played at the moment, and the audio of the speaking object is directly played when the picture in the target video information is displayed. Because the background image is virtualized, the background audio matched with the background image is played, that is, virtualized, and for the video conference, it is more important for the user to play the audio of the speaking object. Therefore, the voice of the speaking object in the displayed target video information is clearer, the user can listen to the voice more clearly without noise, and effective communication and discussion of conference contents of the video conference are guaranteed.
And step 211b, the electronic equipment controls to play the target background audio of the target video information under the condition that the background image is determined not to be the virtual background image.
In the embodiment of the present application, the video information to be displayed includes a video conference for explanation: if the function corresponding to the configuration parameter of the virtual background image is determined to be forbidden, the background image in the video information to be displayed and the target video information is not the virtual background image at the moment, and then the user pays attention to the background image in the video information at the moment; then, for vividness, reality and conference effect of the video conference, the audio of the speaking object can be directly played when the picture in the target video information is displayed, and the target background audio also needs to be played; therefore, the conference participants in the video conference can participate in the conference more personally; in a feasible implementation manner, if the video conference is a conference about an environment protection subject, and the background image is a natural object, the background audio of the video conference can be played as the sound of animals in various natural objects, such as bird cry, so that the conference participants can feel the importance of environment protection more personally on the scene, the content of the video conference is better understood by the conference participants, and the effect of the video conference is ensured.
It should be noted that, for the explanation of the same or similar steps in the embodiments of the present application and other embodiments, reference may be made to the description in other embodiments, which is not repeated herein.
