Abstract: To provide with an effective method for non-photorealistic rendering for computer generated images with pyrography artistic appearances from 2 D images motivates work in this study. The methods proposed in this study are inspired by the improved bilateral filter method and the smooth appearance of the image can be simulated. The character of lines, details in the real pyrograhpy can be simulated by the technique of boundaries enhancing. In addition, the simulating foreground image can be mapped to the background image such as wood, silk etc., in real time. Experimental results show that the proposed method can simulate the real pyrography effect. Because the filter and boundaries enhancing is fast, so the whole rendering can produce final result in several seconds.
