Embodiment 1
[0052] Such as figure 1 Shown in the figure is a generation method of mosaicking target pictures with a picture database, including steps (1)-(8). In Embodiment 1, the target picture is a grayscale picture.
[0053] The invention includes a method for generating a mosaic image, comprising the following steps:
[0054] In step (1), the database images are preprocessed to obtain representative features of each group of database images.
[0055] The database stores pictures such as a large number of photos, digital patterns, letter patterns, color blocks, etc., and is also a candidate picture for filling each area of the target picture. It can also be called a material library, including color pictures and grayscale pictures. In this embodiment, , including at least grayscale images. The features of database pictures are calculated before mosaicing, and can be called at any time to avoid repeated calculation of features of database pictures during the mosaic process, thereby...
Embodiment 2
[0104] Such as figure 1 Shown in the figure is a generation method of mosaicking target pictures with a picture database, including steps (1)-(8). In Embodiment 2, the target picture is a color picture.
[0105] The invention includes a method for generating a mosaic image, comprising the following steps:
[0106] In step (1), the database images are preprocessed to obtain representative features of each group of database images.
[0107] The database stores pictures such as a large number of photos, digital patterns, letter patterns, color blocks, etc., and is also a candidate picture for filling each area of the target picture. It can also be called a material library, including color pictures and grayscale pictures. In this embodiment, , including at least color images. The features of database pictures are calculated before mosaicing, and can be called at any time to avoid repeated calculation of features of database pictures during the mosaic process, thereby reducin...
