摘　　要：针对现有的计算机非真实感绘制(NPR)技术关于素描画的绘制方法的实现效果与手绘风格存在一定差异的问题,设计了一种能够产生层次素描纹理的方法,并将其与多像素宽边缘线条融合,生成具有层次感素描纹理的素描画。首先对原始图像做去噪、增强等预处理,用微分算子提取多像素宽的轮廓线条;再通过膨胀和腐蚀处理并将结果相减生成多层双边轮廓线条,用运动模糊处理多层双边线条得到素描纹理;最后融合边缘和素描纹理,得到素描效果图像。通过对不同特点的图像进行实验,证明该方法得到的素描画的效果比较接近手绘风格。The existing technique of computer Non-Photorealistic Rendering （NPR） on sketch drawing always has some differences from hand-drawing. In order to solve the problem, a method was designed which can generate sketch levels, and integrate with multi-pixel-wide lines to generate sketches which has sketch texture with sense of hierarchy. First, pretreat the original image by denoising and enhancement, adopt differentiation to extract multi-pixel-wide contour lines, use dilation and erosion and subtract the result to generate multi-layer bilateral of contour lines, then take the processing of motion-blur to multi-layer bilateral of contour lines to generate sketch texture, and finally, integrate edge and sketch texture, thus completing images sketching. Through lots of experiments on images of different features, it is proved that the results of the method are more close to hand-drawing style.
