Problems solved by technology
[0004] However, the above method simply shrinks a picture and fills it into small mosaic blocks. It is difficult for users to distinguish the content of the filled picture in each small block of the mosaic picture. Therefore, the mosaic picture made by the existing method Poor readability and legibility

Embodiment Construction
[0200] The first embodiment of the present application provides the first mosaic image generation method, please refer to figure 1 , the method includes:
[0201] Step S101, pre-create a filling image database, the filling image database records image subject features extracted from candidate images and candidate filling images corresponding to the image subject features.
[0202] A filling image database is created in advance, and the created filling image database is used to provide filling images for mosaic image generation.
[0203] Compared with the filling images in the traditional database, the candidate filling images in the filling image database created in the scheme of the present application are images formed after extracting the subject features from the original candidate images. Therefore, the content recorded in the filling image database includes the above-mentioned candidate filling image and subject characteristic information of the candidate image.

The present invention relates to a mosaic image generation method, a mosaic image generation apparatus and an electronic device. The mosaic image generation method includes the following steps that: a filling image database is created in advance; an image to be processed is divided into a plurality of mosaic unit blocks; color feature extraction is performed on the mosaic unit blocks, and the color feature values of each mosaic unit block can be obtained; candidate filling images are searched in the filling image database based on the color feature values of the mosaic unit blocks; the filling images are made to fill the mosaic unit blocks, so that a mosaic image can be formed. According to the method of the invention, content recorded in the filling image database contains the above candidate filling images and the main body feature information of the candidate filling images; the candidate filling images stored in the database are formed after main body feature extraction of images, and therefore, after the mosaic unit blocks are filled with the candidate filling images, the formed mosaic image has high identifiability.
Description
technical field [0001] This application relates to the field of image information processing, in particular to six mosaic image generation methods. Corresponding to the above method, the present application also relates to six mosaic image generating devices and an electronic device. Background technique [0002] Mosaic is a common processing method in image processing. Using image information to generate mosaic pictures can not only create a new visual experience mode for users, but also present more visual information for users. [0003] The existing mosaic generation technology is to divide the picture to be processed into several small blocks, and calculate the color mean value corresponding to each small block, and search for matching pictures from the preset image database according to the color mean value of each small block. Fill the corresponding small blocks with the searched matching pictures, and the final generated picture is a mosaic picture. [0004] However...
