Traditionally

the non-photorealistic rendering pyrography technology has the problems of a low rendering speed and of a single background; therefore details cannot be reflected in the final artistic effect. In this paper

a new measurement model about pyrography simulation based on the deviation mapping is proposed to avoid these disadvantages. First

the background of the pyrography could be obtained based on the texture synthesis technique. Many optimizations such as searching along a spiral path

edge expansion

L2 distance computing predigesting accelerated synthesis speed and the final results is also advanced. Second

based on the tensor field

the foreground image is filtered based on the anisotropic and line integral convolution methods to show enjoyable style features. The technique of image enhancement is also used to enhance the local structure and details. Additionally

the Phong illumination model is used to map the foreground image to the background image. Experimental results show that the details and freehand enjoyable character can be produced. So

the proposed method can simulate the real pyrography effect.
