摘要： Water-shed算法是一种形态学的图像分割算法,但由于其对噪声十分敏感,分割结果往往存在过度分割的现象。该文提出一种基于小波分析的Watershed算法,充分利用小波的多分辨率特性有效地解决了Watershed算法的过度分割问题,并大大提高了分割计算速度。

Abstract: Watershed algorithm is a kind of image segmentation algorithm based on mathematical morphology. The high sensitivity of the watershed algorithm to noise yields a very large number of catchment basins, lead to oversegmentation. A watershed algorithm based on wavelet analysis is proposed to overcome the oversegmentation. It uses the multiresolution of wavelet transform to overcome the oversegmentation and improve the compute speed.
