As shown in FIG. 3 , it is a schematic diagram schematically showing an atlas selection process. Exemplary shown in Fig. 3 collage interface 3 is displayed with atlas selection area 31; Shows a plurality of material atlases in atlas selection interface 32 (exemplarily shows six alternative material diagrams in Fig. 3 set, respectively represented as material atlas 1, material atlas 2, material atlas 3, material atlas 4, material atlas 5, and material atlas 6), each material atlas has a selection box (exemplary in Figure 3 After the user completes the material atlas selection operation, the thumbnails of all material atlases selected by the user are displayed in the collage interface 3 according to the user's selection order (two material images are exemplary shown in FIG. 3 set, and three material images in the material atlas are shown in the thumbnail of each material atlas, respectively represented as material image 1, material image 2 and material image 3) and the atlas selection area 31.

As shown in Figure 4, in one embodiment, before step S101, including:

Step S401, perform image recognition on the material images to be classified, and classify the material images containing the same elements into the same type;

Step S402, generating at least one material atlas, and adding material images of the same type into the same material atlas.

In the application, in order to facilitate users to select the material atlas they need, it is necessary to classify material images in advance, divide material images containing different elements into different types, and add material images of the same type to the same material atlas, and users can Each material atlas is named. Elements in the material image may be human faces or objects, and the material image may also include a specific scene composed of various elements.

As shown in Figure 5, in one embodiment, step S401 includes:

Step S501, when the user's template material image selection operation is detected, the material image selected by the user is acquired as the template material image;

Step S502, performing image recognition on the template material image, and acquiring elements in the template material image as target elements;

Step S503 , performing image recognition on the material images to be classified according to the target elements, and classifying the material images containing the target elements into the same type.

In the application, when the user needs to filter a material image containing a specific element from the material images to be classified and add it to the same material atlas, he can select a material image containing the specific element as a template material image, so that the system The specific element in the material image of the template can be automatically identified, and then other material images containing the specific element can be identified from many material images to be classified.

In the application, the material image selected by the user in step S501 may be one of the material images to be classified or classified, and the template material image selection operation may be any trigger operation on the material image selected by the user. In steps S502 and S503, according to the different types of elements in the template material image, corresponding image recognition algorithms can be used for image recognition.

Users can also select multiple material images containing different elements or scenes as template material images at one time, so that the system can quickly generate multiple different material atlases based on all template material images at one time.

Step S102 , dividing the target image into a preset number of sub-image regions corresponding to the width of the preset color gamut range, and generating mosaic feature information of the target image.

In the application, the preset color gamut range can be pre-defined by the user. If the user does not set it in advance, the system default color gamut range or the color gamut range set by the user last time will be used. The width of the preset color gamut range is negatively related to the number of sub-image regions and the number of material images required to be stitched to form the target image. The wider the preset color gamut range, the less color grading is required, and the fewer sub-image regions and the number of footage images required, and vice versa.

In the application, the user can customize and adjust the preset color gamut range according to the number of material images. For example, if the user initially sets the preset color gamut range, the target image is divided into the first number (for example, 80×60) sub-image area, corresponding to the first number of material images; if the number of material images in the material atlas selected by the user is insufficient, the user can adjust the preset color gamut to make the preset color gamut wider, so that the target image is captured Divided into a second number (for example, 40×30) of sub-image areas, the corresponding second number of material images is required; if the number of material images in the material atlas selected by the user is still insufficient, the user can continue to adjust the preset color gamut range , until the number of material images in the material atlas selected by the user is sufficient. If the number of material images in the material atlas selected by the user is insufficient and the user has not adjusted the preset color gamut range, the system can also adopt the method of multiplexing material images by default to complete the collage. According to actual needs, set in at least two sub-image areas The same material image, reuse the same material image.

In the application, the collage interface displays a color gamut range setting area, which can be a color gamut range input box, a color gamut range adjustment progress bar, a color gamut range selection button or an icon.

In the application, the collage feature information includes the number of sub-image areas and the size and color value of each sub-image area. Footage image.

Step S103 , according to the collage feature information and the image feature information, select material images whose image feature information matches the collage feature information from the at least one material atlas as selected material images.

In the application, the material atlas can be the material atlas selected by the user, or the material atlas selected by the system by default. The size and color value of the material image in the material atlas may not match the size and color value of the sub-image area. Therefore, it is necessary to filter out the material image whose image feature information matches the collage feature information, and then use it as the selected material image for collage.

Step S104, stitching the selected material images to form a stitching effect map of the target image.

In the application, the mosaic effect image is an image that is completely identical to the frame of the target image formed by mosaicing multiple selected material images.

As shown in Figure 6, in one embodiment, step S103 includes:

Step S601. According to the color value of each sub-image area, select a material image matching the color value of each sub-image area from the at least one material atlas, as a selected material image, one of the The sub-image corresponds to one of said selected material images;

Step S104 includes:

Step S602, according to the size of each sub-image area, crop or enlarge the selected material image corresponding to each of the sub-image areas, so that each of the sub-image areas is the same size as the corresponding selected material image ;

Step S603, according to the position of each sub-image area, place the selected material image corresponding to each sub-image area in the corresponding position in the target image, and stitch to form a mosaic effect diagram of the target image .

In the application, in step S601, the matching of color values means that the color values are the same or belong to the same color gamut; Select the footage image so that both are the same size. The cropping method can be center cropping or cropping with the position of the target element in the selected material image as the center, so that the selected material image after cropping contains the target element and has the same size as the sub-image area.
