An Interactive System for Generating Low Polygon Style Maps

Abstract

The invention discloses a low polygon style graph generation interactive system, which includes: a vertex sampling and grid generation module, which is used to perform vertex sampling on the basis of maintaining the content structure of the input image, and uses an adaptive thinning algorithm to refine the vertices according to their Sort the importance, and then select the top K vertices from the sorted vertices according to the number K of vertices fed back by the interaction module, and use Delaunay triangulation to generate the mesh; the mesh rendering module is used to create the triangle mesh Lattice coloring is used to obtain a low polygon style map, in which the light and dark contrast between adjacent triangles is improved by setting the minimum brightness difference. The relevant minimum brightness parameters are fed back by the interaction module; the interaction module is used to realize the interaction between the system and the user. The number of vertices K and the minimum brightness parameter input by the user are received through corresponding tools. The system is computationally low and can easily and quickly generate low-polygon style maps.

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...
