The following describes a process of a character recognition display provided in an embodiment of the present application with reference to the drawings.

A flow diagram illustrating a method of person identification presentation according to some embodiments is illustrated in fig. 6. In connection with fig. 6, the method comprises the steps of:

s610: and receiving an identification instruction, wherein the identification instruction is used for capturing a screen of a display interface displayed by a display and generating a screen capture image.

In the embodiment of the present application, when a user views the media assets displayed by the display device 200, if the user wants to further know the character information in the current display interface, an identification instruction may be sent to the display device 200. That is, the controller 250 in the display device 200, after receiving the identification instruction, can know the information that the user wants to know the person in the currently displayed interface of the display according to the identification instruction.

In one implementation, the user may send an identification instruction by using a "screenshot" key set on the remote controller, or by using a specific key of the remote controller bound with the screenshot function, for example, binding a favorite key of the screenshot function or a live key of the screenshot function. When a user watches the media assets, if the user wants to perform screenshot, an identification instruction is sent out through a screenshot key on a remote controller or a specific key bound with the screenshot function.

In another implementation, the user may issue the recognition instruction through a voice input. For example, the user long-presses a voice input key on the remote controller and says "who the person is". The controller 250 first uploads the user's voice input information to the server 400 after receiving the user's voice input. The server 400 analyzes the voice input information, and when the voice input information is analyzed to be information of a person in the current display interface, a screenshot instruction is sent to the display device 200, and the display device 200 performs screenshot on the current display interface of the display 275 according to the screenshot instruction.

In the embodiment of the application, the controller receives an identification instruction sent by a user through a remote controller screenshot key or voice input, and captures a display interface displayed by the display according to the identification instruction and generates a screenshot image, and then acquires identification data in the screenshot image through subsequent steps so as to display the display 275. It should be noted that the screenshot image in the present application may be captured from a movie program, a variety program, a news program, and the like, and may also be captured from a video call, a user self-made video, and the like.

S620: and acquiring the characteristic information of the face to be recognized in the screen shot image.

In the embodiment of the application, after the display device 200 acquires the screenshot image, the screenshot image is sent to the server 400, the server 400 receives the screenshot image, and extracts the facial feature information to be recognized in the screenshot image based on an image content recognition technology, where the facial feature information to be recognized includes extraction of facial features such as forehead, eyebrow, eyes, nose, mouth, and chin. When the face feature information to be recognized is extracted, the position information of each face feature can be marked.

It should be noted that, in the present application, the display device 200 and the server 400 may also be the same device, that is, the functions that can be implemented by the display device 200 and the server 400 may be implemented by the same device, and the specific process is not described herein again.

S630: and when the matching confidence coefficient of the pre-stored face feature information in the database and the face feature information to be recognized does not exceed the preset confidence coefficient, acquiring similar face feature information.

In this embodiment, the server 400 is provided with a database, and the database stores a plurality of pre-stored face feature information, and the database can be regarded as a set of a plurality of pre-stored face feature information in the server. The plurality of pre-stored face feature information refers to face feature information of celebrities, and as the name suggests, the celebrities generally refer to characters with high ability in various industries and high revenues, such as actors, singers, artists and the like, and the celebrities can be well known by most people. After extracting the face feature information to be recognized in the screenshot image, the server 400 compares the face feature information to be recognized with a plurality of pre-stored face feature information in the database one by one to obtain a plurality of matching confidence levels respectively.

In some embodiments, the server 400 is provided with a preset confidence level, and when the obtained matching confidence levels do not exceed the preset confidence level, it may be determined that the matching confidence level of the facial feature information to be recognized and the pre-stored facial feature information of each celebrity in the database is relatively low, so that the facial feature information to be recognized may be facial feature information corresponding to a plain person, where the plain person is an ordinary person in life, and the plain person may be a person who is not known by other people except relatives and friends. For example, the preset confidence level is set to 98%, and if there is no pre-stored face feature information with a matching confidence level of more than 98% between the face feature information to be recognized and the pre-stored face feature information, it may be determined that the face feature information to be recognized is extracted from the plain face. At this time, the server 400 acquires, from the database, pre-stored face feature information whose matching confidence with the face feature information to be recognized satisfies the condition, as similar face feature information. For example, the server 400 may sort the plurality of matching confidence levels in a descending order, and select similar face feature information, the server 400 may feed back the similar face feature information to the display device 200, and the controller 250 acquires the similar face feature information, where the similar face feature information refers to N pre-stored face feature information before the arrangement of the matching confidence levels of the face feature information to be recognized, where N is greater than or equal to 1, that is, when acquiring the similar face feature information, at least the first 1 pre-stored face feature information is selected from the arranged matching confidence levels, and the pre-stored face feature information corresponding to the matching confidence level is used as the similar face feature information.

In some embodiments, when the matching confidence of any pre-stored face feature information in the database and the face feature information to be recognized exceeds a preset confidence, standard face feature information is obtained, wherein the standard face feature information refers to the pre-stored face feature information with the highest matching confidence with the face feature information to be recognized. That is, when any one of the obtained matching confidence degrees exceeds a preset confidence degree, it may be determined that the matching confidence degree of the face feature information to be recognized and the pre-stored face feature information of a celebrity in the database is high, so that the face feature information to be recognized may be regarded as the face feature information corresponding to the celebrity, at this time, the server 400 may select the pre-stored face feature information with the highest matching confidence degree as the standard face feature information, the server 400 may feed the standard face feature information back to the display device 200, and the controller 250 may obtain the standard face feature information. For example, the preset confidence level is set to 98%, if there is pre-stored face feature information with a matching confidence level of more than 98% in the face feature information to be recognized and the pre-stored face feature information, it can be determined that the face feature information to be recognized is extracted from the celebrity face, and the celebrity corresponding to the pre-stored face feature information with the matching confidence level of more than 98% is the celebrity recognized in the screenshot image.

It should be noted that the preset confidence level can be set according to the accuracy of the algorithm, and only when the face feature information to be recognized and the pre-stored face information come from the same person, the matching confidence level of the two can reach above the preset confidence level, which can be up to 100%. If the face feature information to be recognized of the primitive person is matched with the face feature information prestored in the database, the matching confidence may be lower than 50%.

In some embodiments, after selecting the standard facial feature information, the server 400 can know from the standard facial feature information which celebrity person the standard facial feature information is extracted from, and search profile information and related media corresponding to the standard facial feature information according to the celebrity person. After searching the corresponding profile information and the related media assets, the server 400 feeds back the data to the display device 200, and the data is acquired by the controller 250. For example, after the facial feature data to be recognized is acquired from the screenshot image, the facial feature data to be recognized is matched with the prestored facial feature information extracted from Zhang III in the database, the character in the screenshot image can be determined to be Zhang III, and then the brief introduction information of Zhang III, such as Zhang III, is obtained, and is born in Shanghai, and is popular among Men's Singles, movie actors and music producers in China, and graduates in the Gelidon Hotel administration academy. And simultaneously acquiring related media assets of Zhang three participating players. In addition, the eight trigrams of news of Zhang III, etc. can also be used.

the method comprises the steps of respectively obtaining the face feature information to be recognized of a plurality of figures, and respectively obtaining the matching confidence result of each figure, wherein the matching confidence result comprises the matching confidence of each piece of pre-stored face feature information in a database and the face feature information to be recognized. And for each person in the screen shot image, comparing the matching confidence result with the preset confidence. When the matching confidence coefficient result is that pre-stored face feature information exceeding a preset confidence coefficient exists, acquiring corresponding standard face feature information; or, when the matching confidence result indicates that there is no pre-stored face feature information exceeding a preset confidence, acquiring corresponding similar face feature information. It should be noted that, for a plurality of people in the screenshot image, all of the people may belong to the plain face, all of the people may belong to the celebrity face, and also a part of the people may belong to the plain face, and the other part of the data celebrity face, whether the celebrity face or the plain face, is only required to correspondingly obtain similar face feature information or standard face feature information, and further obtain corresponding display data based on the similar face feature information and/or the standard face feature information.
