基于分水岭与多尺度相结合的影像分割方法
A High Resolution Image Segmentation Method of a Combination of Watershed and Multi-scale
摘要
Abstract
Watershed segmentation is a widely used automatic scheme to generate close outlines. It might give rise to closed contour of single pixel width. Using this method the image needs to be divided into many small areas which leads to huge workload. This paper proposes a watershed and multi-scale comprehensive image segmentation method. Firstly, calculate the comprehensive gradient which merges the brightness gradient and the texture gradient by using watershed algorithm,then,merge the area of the smallest homogeneity measure (spectral,shape and texture homogeneity metric),and the last,improve region adjacency graph. The experimental result is compared with watershed and region merging image segmentation algorithm, this method proves that it can not only take the advantage of high resolution remote sensing image features in the spectrum,shape,texture and other characteristics,and reduce the computational time.关键词
