Embodiment 1

[0032] Such as figure 1 Shown in the figure is a method for generating a fragment mosaic picture, including steps (1)-(5).

[0033] A method for generating a fragment mosaic image, comprising the steps of:

[0034] In step (1), the target picture is segmented, and the target picture is equally divided into more than 4 identical rectangular areas, and the pictures in each rectangular area are slices. The target picture here refers to the complete picture to be processed, which may also be called the initial picture. The slice refers to a rectangular image formed after the target image is cut.

[0035] Such as figure 2 As shown in the figure, a fragment mosaic image segmentation processing method is shown in the figure, that is, the target image is divided into 4 slices, including the following steps:

[0036] (101) Determine whether there are divisible pictures to be processed; if yes, perform step (102), if not, perform step (103). A slice refers to a picture that can no...

Abstract

The invention provides a fragment mosaic image generation method. The fragment mosaic image generation method comprises the following steps of: carrying out target image segmentation processing, copying and cutting into slices, confirming target positions of the slices after translation, translating the slices and inlaying the slices at the target positions, completing the mosaic image, and the like. The fragment mosaic image generation method can be used for effectively solving the technical problems of oversized image database, higher cost of image collection, more resources occupied by database, and the like in the prior art. The invention has the advantage of providing a fragment mosaic image generation method which can be used for automatically and quickly generating the mosaic image based on the target image by taking a computer as a tool without needing the image database, and can achieve the fragment mosaic effect only by copying, moving and inlaying the slice image into a target area from the target image.

Description

technical field [0001] The invention relates to the field of digital image processing, in particular to a method for generating fragment 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...
