Abstract
The images generated from image sketch generation algorithm are always not enough fine and have a low efficiency in the sketch image generation. In the view of this problem,a image sketch generation algorithm is proposed based on Discrete Wavelet Transform(DWT). The first step is to convert the true color image to a grayscale image,through the fast wavelet forward transform,the low frequency coefficient,fast wavelet inverse transformation and other ways are removed to extract image edges. Then,the each point of grey value is placed upside down,and then through the image sharpening and smoothing processing to real?ize the image sketch effect. The experimental results show that the algorithm is fast and efficient. What's more,it reserves nicely the detail characteristics of the input image.关键词
