Mosaic processing method of 2D picture

Abstract

The invention provides a mosaic processing method of a 2D picture. The method is characterized by comprising the following steps that a) an original picture is pre-cut, and the pre-cut picture is divided into color blocks; b) a primary color building block closest to each color block is searched, and an building-block effect of the picture is optimized; and c) the closest primary color building blocks are used to carry out color filling on the corresponding color blocks, and a modularized mosaic picture is obtained. Compared with the prior art, the method of the invention has the advantages that The picture processing method is simplified, fewer building block colors are used to form the modularized mosaic picture, a visual effect closer to the original picture can be obtained when the picture is observed from a position far away, splicing can be completed via building blocks of fewer colors, and the production cost is reduced effectively.

Description

technical field [0001] The invention relates to a mosaic processing method for two-dimensional pictures. Background technique [0002] The so-called adding a mosaic to a picture refers to dividing the original image into several small areas through a processing method, each area is called a color block, and a new solid color similar to the original image is used for each color block. The color of the block is replaced, so as to obtain a process of blurring the artistic effect. [0003] Jigsaw puzzle is a kind of intellectual game which is very popular. It has many changes and different difficulties, which makes people never get tired of playing it. At present, puzzles are usually realized by dividing a picture into multiple puzzle units. This method can ensure that the spliced ​​jigsaw puzzle is a complete picture, but different jigsaw puzzles will use different jigsaw units, making it difficult to reduce the cost of the jigsaw puzzle, and the jigsaw puzzle unit of a jigsa...

Problems solved by technology

[0008] 1. Classify the color blocks, and use the same matching method for each color block. During the matching process, the color characteristics of each color block are mainly investigated. However, due to the relatively small number of primary colors of the building blocks (due to production costs and difficulty, etc.) Considering factors, there are about 40-50 kinds of primary colors of building blocks), the clarity of the assembled picture is poor, and it is difficult to get a better visual effect, because the color of each color block is only the "color" of the pixel in the original image in this color block Average value", for example, if there are 4 pixels in a color block, 3 of which are light gray and one is dark black, the average value is the general gray, but in fact the light gray color works better;
