摘要
小波变换是时间频率的局部化分析,它可以通过伸缩平移运算对信号逐步进行多尺度细化。本文正是基于小波变换在图像处理领域中表现出的多尺度分析,提出了用小波变换检测活塞环图像边缘的方法,这种方法通过对二维小波变换图像局部极大值的检测得到图像的边缘信息。通过实验证明了这种方法的有效性。
The wavelet transform is the localization analysis of time and frequency, and it can multi-scale refine the signal by calculating of flex and transition. This paper presents a method of using the wavelet transform to detect the image of piston ring edge based on the multi-scale analysis of the wavelet transform in the image processing field. The method acquires the information of the image edge by detecting the image local maxima of the two-dimension wavelet transform. The experiment proofs the availability of this method.
