Abstract: A new automatic algorithm，based on 2D image，for rendering crayon style paintings is proposed in the paper.By analyzing the structure characteristics and artistic features of real crayon drawing texture，and abstracting a simple model of crayon drawing，an exploratory noise texture method is proposed，crayon style rendering for color and contour of the image is realized respectively，and the FLIC algorithm is used to generate the trend texture of stroke in the YIQ color space，so that the final result is very similar to hand-painted effect，and achieves the purpose of crayon drawing style rendering with computer aided design.
