摘要

本文描述了一种新的门限选择方法，它基于小波变换多尺度方法分析图像直方图的信息．通过对小波变换后直方图零交叉点检测，得到一序列门限，用于描述图像的边缘特征．整个方法采用一种由粗到细引导的多分辨率门限结构．

Abstract

A new method of analysis for threshold selectionis presented. It is based on the wavelet transform which provides a multiscale analysis of the information of the histogram of an image. By the detection of the zero-crossings of the wavelet transform of the histogram

a sequence thresholds of the histogram is abtained

which are used to describe the image edge features. The complete method uses a coarse-to-fine multiresolution threshold stategy.
