摘要
图像分割是图像理论发展的瓶颈,过渡区是指图像中介于目标和背景之间的特殊区域,借助于过渡区的确定进行图像分割。主要介绍了过渡区提取的两大类方法:基于梯度的方法和基于非梯度的方法,并对提取效果以及存在的问题做了简要分析。
Image segmentation is treated as a key issue in image processing and machine vision, and has been the bottleneck of development. Transition region is a special region located between the object and background. Having the aid of extraction of transition region to segment image is a kind of burgeoning technology. Two kinds of methods have been introduced： methods based on gradient and methods based on non-gradient. Briefly, the extracted effects and existent problem have been analyzed.
