Pencil sketch render method based on HTML5 platform

A non-photorealistic pencil sketch render method is achieved by improving the pencil texture simulation algorithm which is based on motion blur filter.By using Unsharp Mask(USM)sharpening which is based on Gaussian blur,the input image can be sharpened into a pencil sketch base map.Pencil texture can be generated by the motion blur algorithm.After sharpen filtering,merging the motion-blurred image with the edge-extracted one,the pencil sketch effect is achieved.This method is realized on the HTML5 platform.The result shows that it is a fast approach and very realistic,as well as hierarchic.It proves to be suitable in Web application.
