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...

Abstract

The invention provides a mosaic image generation method. The mosaic image generation method comprises the following steps of: database image preprocessing, target image segmentation processing, taking any one of slices, selecting an image to be inlaid from database images, scaling processing of the image to be inlaid, inlaying processing, completing the mosaic image, and the like. The mosaic image generation method effectively solves the technical problems of oversized image database, poor visual effect after the target image is inlaid, easiness in distortion of details of the mosaic image, and the like in the prior art. The mosaic image generation method can be used for automatically and quickly generating the mosaic image corresponding to the target image based on different database images by taking a computer as a tool. The mosaic image generation method does not change colors of the database images without distortion or strict requirements for the database size, and can complete the mosaic image by using a smaller image database.

Description

technical field [0001] The invention relates to the field of digital image processing, in particular to a method for generating mosaic pictures. Background technique [0002] Image mosaic technology refers to arranging and splicing multiple small images (photographs, digital patterns, letter patterns, color blocks, etc.) into a large image. The distance between the image viewer and the image is different, and the visual effect of the image is also different. When the distance is short, the viewer sees small images arranged together, and even the details of each small image can be seen; when the distance is long, the viewer pays more attention to the overall visual effect of the large image, The original small image becomes a part of the large image, even if the viewer can clearly distinguish the local details of the small image, but the overall visual effect of the large image is more obvious and more attractive. [0003] The existing image mosaic technology mainly includes...
