摘　　要：研究了小波变换在二维图像处理中的多分辨率分析特性,提出了一种基于小波多分辨率分析的线条画生成方法,并采用MATLAB语言进行了编程实现。将彩色图像转换为灰度图像,采用bior1.1小波对灰度图像进行二层小波分解,滤除分解系数中的低频系数进行图像重构,并通过反向、滤波和亮度调整等一系列处理,最终获得一种模拟手绘线条画的效果图。试验结果表明,用该方法生成线条画效果图是行之有效的。The multi-resolution analysis characteristic of wavelet analysis in the 2D image processing is researched.A method of linedrawing generation based on multi-resolution analysis of wavelet is provided,and it is realized in MATLAB language programming.A color image is converted to a gray image,and using bior1.1 wavelet the gray image is made decomposition for 2-layer.Then the lowfrequency part of the decomposition coefficients is filtered out,and the image is made reconstruction.After a series of treatments of reverse,filter and grayscale adjustment,the effect of hand-drawn line-drawing is obtained ultimately.The experimental results show that the rendered image of line-drawing generated by this method is effective.
