摘要:

本文研究了小波变换在图象识别中的应用，首先针对具有封闭轮廓的二维形状，提出了一维的“规一化曲率函数”表示法，然后采用一种特殊类型的小波基对上述一维函数进行小波变换，最后根据其过零特性提出了“基于小波变换过零特征的二维形状识别方法。”

Shape Recognition Based on Wavelet Transform

()

Abstract:

:This paper discusses the application of wavelet transform to image recognition.For the 2D shape with closed contour,a normalized curvature function is used to reduce 2D signal of contour coordinate to 1D signal.Using the zero crossing of wavelet transform obtained through a special wavelet bases,a new approach,2D Shape Recognition using Zero crossing of Wavelet Transform,is proposed.
