An Interactive System for Generating Low Polygon Style Maps

Abstract

The invention discloses a low-poly image generation interaction system which includes a vertex sampling and mesh generating module, a mesh rendering module, and an interaction module. The vertex sampling and mesh generating module is used for sampling vertexes on the basis of keeping the content structure of an input image, sorting the vertexes by importance through an adaptive refinement algorithm, selecting the first K vertexes from the vertexes after sorting according to the number of vertexes K fed back by the interaction module, and generating meshes through Delaunay triangulation. The mesh rendering module is used for coloring the triangular meshes to get a low-poly image, wherein the brightness contrast between adjacent triangles is improved by setting a minimum brightness difference, and the relevant minimum brightness parameters are fed back by the interaction module. The interaction module is used for realizing the interaction between the system and users and receiving the number of vertexes K and the minimum brightness parameters input by users through corresponding tools. The system needs less amount of computation, and can generate a low-poly image easily and quickly.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an interactive system for generating low-polygon style maps. Background technique [0002] In recent years, low-poly stylized images have become increasingly popular in non-photorealistic renderings of photographs due to their 3D abstraction. At present, most methods for generating low-polygon style maps require users to have a certain understanding of 3D modeling and require a lot of work. At the same time, the generated low-polygon style maps are not ideal. For example, if you directly use the software TRIGRAFF to generate, more details will be lost. As another example, the paper (M.Gai and G.Wang: Artistic low polyrendering for images. The Visual Computer: International Journal of Computer Graphics), the disclosed algorithm is guided by a characteristic flow field, and the generated results are in such fields as hair, hat decoration, etc. Too much texture will be pr...
