图像分割的多尺度方法研究

作为一种典型的多尺度(或多分辨)分析工具,小波变换已经在很多的信号与图像处理的任务中得到了成功的应用。首先分析了现有的图像分割方法,指出了图像的多尺度特性,以及利用小波变换挖掘图像的多尺度特性的必要性。在分析了小波变换的原理、步骤的基础上,研究了多尺度方法在图像分割问题中的应用。

Analysis of Image Segmentation Based on Multi-scale Method

As a typical multi-scale(or multi-resolution) analysis tool,wavelet transform has been successfully applied in a lot of signal and image processing tasks in various kinds of engineering fields.In this paper,we first analyze the existing image segmentation methods,and then point out that the multi-scale features of the image,as well as the need for mining multi-scale image features using wavelet transform.Based on an investigation of the wavelet,we analyze the feasible of wavelet transform in image segmentation.
