-
摘要: 基于现有的小波去噪方法和边缘提取方法,提出了一种通过自适应阈值设定的小波边缘提取算法,从而改进了传统方法中通过固定阈值进行小波边缘检测中存在的问题,通过对相关图像的分析结果可以看出,该方法能够较好地对图像边缘进行自适应检测,达到了较好的效果.Abstract: Based on the existing wavelet denoising and edge detection method,this paper proposed a wavelet edge detection algorithm by set adaptive thresholds.Thus deduced the error in traditional method by set fixed threshold.The analysis results are shown that this method can detect the image edge adaptively and achieve a good result.
