Description

Mask operation method and equipment, storage medium and terminal thereof

Technical Field

The present disclosure relates to the field of computer technologies, and in particular, to a mask operation method and apparatus, a storage medium, and a terminal.

Background

With the rapid development of computer technology, terminal applications for processing pictures, such as a camera, P-picture software, social APP, etc., can be installed in terminal devices such as smart phones, palm computers, tablet computers, etc., and users can add special effects, decorate and beautify, make-up, change figures, etc. to original pictures (such as figures, landscapes or buildings, etc.) or videos based on the terminal applications.

Among various image processing modes, masks are widely used in image processing to selectively apply operations or effects to specific areas of an image. Conventional masking techniques typically involve pixel-level masking or vector masking to define the region of interest. A pixel mask consists of a binary value assigned to each pixel in the image, where a value of 1 indicates that the pixel is contained in the mask and a value of 0 indicates that it is not contained in the mask. Vector masks, on the other hand, employ vector-based representations, such as curves or shapes, to define regions of interest. However, existing image processing systems or tools have limitations in terms of the functionality and flexibility provided by masking.

Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The mask operation method provided by the embodiment of the application can be applied to various image processing software or video processing software. The mask operation device according to the embodiment of the present application may be a tablet computer, a smart phone, a palm computer, a Mobile Internet Device (MID) and other terminal devices with an image processing function, or may be an application server with a computer processing capability used when the mask operation is performed by a repair type terminal application.

The mask operation method provided in the embodiment of the present application will be described in detail with reference to fig. 1 to 8 c.

Referring to fig. 1, a schematic flow chart of a mask operation method is provided in an embodiment of the present application. As shown in fig. 1, the method of the embodiment of the present application may include the following steps S101 to S103.

S101, generating a mask layer based on a preset mode.

It should be noted that, the mask layer may be generated in various ways, and commonly used masks generally include a layer mask, a vector mask, a fast mask, a paste mask, and a mixed color band, where the layer mask may also be a pixel mask. Masks that may support user creation in this embodiment may include at least layer masks and vector masks.

In this embodiment, at least one operation tool or operation software or terminal application capable of processing a mask may be installed in the mask operation device. The operations performed by the mask operating apparatus described in this embodiment can be understood as operations performed by the mask operating apparatus depending on the tool for mask operation.

In this embodiment, the target image may be a target layer, and the effect image may be an effect layer.

In one embodiment, the mask manipulation device at least supports a user to define a region of interest with an arbitrary image as a pixel mask. In one implementation, the mask operating device may obtain and identify a pixel operation instruction of a user based on a user operation page or a user input, and further select an image as a pixel mask according to the pixel operation instruction. For example, the mask operating device may acquire the pixel operation instruction of the user through different instruction acquisition modes such as a mouse, a keyboard, a touch screen, or voice recognition.

The mask operating device may recognize gray information of an image after selecting the image according to a user operation and convert the gray information into transparency information of an alpha channel. The gray scale information and/or transparency information may be understood as a gray scale map, for example a picture of a 32-bit band transparency channel may be converted into a gray scale map. In this embodiment, the finally obtained gray-scale image may be used as a mask layer that can be applied to the target image. The target image may be understood as an image that the user wants to modify or edit or manipulate.

In one embodiment, the mask operating device may obtain the mask layer based on the created vector information, where the created vector information may be created by the user according to the authoring requirement of the user, or may be vector information pre-stored in the mask operating device and used as a template. The so-called vector information may include at least some paths or graphics or any other information that enables a vector mask to be obtained. In this embodiment, the mask operating device may define the region of interest based on a vector-based representation of the user operation. The expression vector-based means is understood to mean an operable object formed based on the above-mentioned vector information, such as an image formed by an arbitrary regular or irregular vector graphic or a vector path formed by arbitrary path information, and the vector expression shown in fig. 2 may be a vector object of a mask. The mask manipulation device may extract transparency information and/or inversion information for any vector representation or vector-based representation to obtain a mask layer. For example, the mask operating device may perform α -channel recognition, that is, transparency information recognition, on the vector object shown in fig. 2 to obtain transparency information shown in fig. 3, and may invert the α -channel thereof to obtain inverted information shown in fig. 4, and after obtaining the inverted information, may apply the information to the target image to perform mask processing on the target image. For example, the target image in fig. 5 is a mid-autumn night image, and the effect image shown in fig. 6 can be obtained by masking the target image with the inverted information of fig. 4.

In the process of generating or creating a mask, in the operation page shown in fig. 7 displayed by the mask operation device, a mask may be created, that is, generated using a bottom menu of the operation page.

In one embodiment, the mask manipulation device may provide a plurality of creation forms of blank masks, conformal masks, preset masks, and body masks. When the function of the blank mask is triggered, the blank layer mask can be built on the selected layer or layer group, and a different instruction input mode is adopted, for example, alt is pressed to click the function to build the full black layer mask. When a selection is present, manipulating the blank mask can create the same mask as the selection (e.g., white in the selection and black outside the selection). When the function of the isomorphism mask is triggered, the mask can be established on the selected layer, and the mask is the inverse of the layer alpha channel information. When the function of the preset mask is triggered, some menus can be automatically popped up, so that a user can add the preset mask in the menus. When the main body mask function is triggered, image information of a layer can be uploaded, an online service of general high-definition segmentation is called, a result is obtained, an alpha channel of the result is identified, a black-and-white picture is obtained, and the result is used as a mask to be applied to the layer. In one implementation, the mask layer may also be dragged into the target area quickly as a mask layer.

It can be appreciated that the mask layer generated or created in any way can be used for performing mask operation on the target object immediately, or can be temporarily stored or permanently stored in the mask operation device, so that the mask layer can be called at any time when a user needs to use the mask layer. The masking operation on the target object is understood as an operation of applying a mask to the target image to merge the target image into a mask layer to obtain an effect image.

In this embodiment, the mask operation device allows the user to generate a mask more flexibly to meet the requirement of editing an image by himself, for example, mask inversion using inversion information may be used in vector mask generation or in vector mask generation. That is, the present embodiment first provides a more flexible operation method for generating a mask.

S102, processing the mask layer according to the obtained mask operation instruction.

In this embodiment, the mask operation device may select and process a mask layer according to a mask operation instruction input by a user, where the selected mask layer may be the mask flexibly created by the user, or a common mask stored in the mask operation device in a history manner, or a mask downloaded online from a network in time. It should be noted that, the mask that can be imported into the operation page and processed is within the protection scope of the present embodiment. In this embodiment, the mask operation instructions include at least one of editing a mask, applying a mask, inverting a mask, enabling or disabling a mask, and deleting a mask. It will be appreciated that processing the mask layer may include at least one of editing, applying, inverting, enabling or disabling, and deleting the mask layer. It will be appreciated that processing the mask layer may also include some of the operations described above for manipulating the mask, for example, all of the operations for applying the mask to the target object to obtain the effect image.

In this embodiment, editing the mask may include at least an independent operation on the mask layer. That is, the editing operation of the mask can be understood as a special display mode, and the mask can be edited more intuitively. In the process of editing the mask, the selected mask can be independently displayed in an operation page or canvas, and the layer and other layers and masks are not displayed. In one embodiment, the various operating functions and operating logic are consistent with a main interface in the mask edit mode, where the main interface may be the main page of the mask operating tool.

In one implementation, a mask operation instruction to edit a mask may be input based on different operation modes, such as editing a selected mask by clicking or double clicking on a mask thumbnail.

In this embodiment, applying the mask includes at least an operation of layering the selected mask onto the target image to obtain the effect image. In one implementation, the selected mask can be directly dragged to the target image to realize the superposition of the images to obtain the effect image, or the mask can be applied in a pasting mode or in a mode of importing or inserting the images.

In this embodiment, the inverse mask includes at least a process of inverting the mask layer according to transparency information of the selected mask layer and applying the inverted mask layer to the target image. In one implementation, the operation of inverse display may be performed in the mask object region by an operation mode such as a mouse or a touch screen.

In this embodiment, disabling the mask includes hiding the mask layer in the currently displayed page. By hidden it is understood that it is not shown, but does not represent deleted. And the display can be redisplayed, namely the starting can be realized when the display needs to be used. In one implementation, the activation or deactivation of the mask layer can be implemented in cooperation with left and right mouse keys and the like.

In this embodiment, deleting the mask includes at least releasing the corresponding relationship of the mask layer and the effect image. That is, the effect obtained by applying the mask layer to the effect image is removed, and the original target image is restored. In one implementation, the mask layer of the effect image may be deleted directly after the deletion of the mask is displayed by the right key in the mask object area. In one implementation, the mask layer or the mask object can be directly dragged out of the target layer, so that the mask layer can be kept to be an independent layer, and the association relation between the mask layer and the original target image is relieved. In this embodiment, the mask layer after the mask operation is deleted may also be stored in the mask layer stored in the history.

S103, displaying the mask layer and/or the target image based on the corresponding selectable state.

In this embodiment, the effect image obtained by applying the mask layer has a plurality of selectable states. For example, at least one of the general selection state, the independent selection layer state and the independent selection mask state shown in fig. 8a to 8c may be used. Wherein the thumbnail representations with the slash in fig. 8 a-8 c represent the mask layers that are deactivated. This state can be entered when an area other than the thumbnail of the mask layer is clicked or when a layer corresponding object is selected in the layer in the general selection state shown in fig. 8a (in this state, the style is similar to that of selecting a layer without a mask layer). When the universal selection state is used, a selection tool is used, a deformation frame in the canvas is in a state when a target image is not superimposed with a mask layer, the target image and all mask layers on the target image can be changed simultaneously when the deformation frame is moved and deformed, and only the target image is changed when the selection tool and tools (pixel class or vector class) corresponding to the attribute of the image layer are used for editing, so that the mask layers on the target image are unchanged. In the independently selected layer state shown in fig. 8b, this state can be entered by clicking on the layer thumbnail, increasing the number of pounds around the layer thumbnail by a dashed line of 1. In this state, the selection tool is used to change the target layer independently during movement and deformation, and all mask layers on the target layer are unchanged. The remaining operational rules may be consistent with the general state. In the independently selected mask state shown in fig. 8c, a new mask layer may be generated. This state can be entered by dragging other layers into the mask layer, clicking the mask layer thumbnail, and increasing the number of pounds of dashed lines around the mask layer thumbnail by 1. In the state, a selection tool is used, a deformation frame in the canvas is the state of the mask layer, and the mask layer is independently changed when moving and deforming. When the selecting type tool and the tool corresponding to the mask attribute are used for editing, only the mask layer is changed, and the target layer where the selecting type tool and the tool corresponding to the mask attribute are positioned is unchanged. In one implementation, multiple mask layers can be selected by ctrl+clicking in the state, and when multiple mask layers are selected, the deformation frame in the canvas is a combination of mask ranges, and the selected mask layers are moved and deformed simultaneously.

The embodiment can perform various different operation treatments on the generated or created or historically stored mask layer, so that the related functions of the mask are wider, the image technology is more accurate and flexible, meanwhile, the novel mask function simplifies the workflow of an image editor, and the efficiency of image processing is improved. In addition, pixel masking and vector masking techniques provide greater precision in defining regions of interest during mask generation or creation, thereby enabling more accurate and targeted modification of images.
