This paper mainly discusses the design and implementation of Chinese ink painting style rendering algorithm based on weighted least square filtering.The innovation of this paper is to put forward the idea of applying weighted least squares filtering to ink painting style rendering,and build a relatively simple ink painting diffusion model.The model can make the target image automatically generate ink painting effects with different degrees of abstraction and diffusion effects.Finally,this paper further proposes to use GPU to speed up the hardware processing of the whole algorithm,and the experiment has achieved good synthesis effect.
