A Region Merging image segmentation algorithm based on boundary extraction is disclosed, comprising the steps of calculating a gradient image, extracting a boundary and carrying out initial segmentation and Region Merging, wherein each pixel is regarded as one region when initial segmentation is not ...
Image segmentation aims to partition an image according to the objects in the scene and is a fundamental step in analysing very high spatial-resolution (VHR) remote sensing imagery. Current methods struggle to effectively consider land objects with diverse shapes and sizes. Additionally, the ...

This paper presents a novel region merging segmentation method for color image based on color and texture distribution features. The segmentation strategy includes two phases. In the first phase, we select initial seed points for superpixels extraction in the texture energy image at average intervals....

In this article, we propose a fast superpixel region merging algorithm for synthetic aperture radar (SAR) image segmentation. With our previously proposed adaptive superpixel generation approach (ALFCE), an initial over-segmentation superpixel map for SAR imagery can be obtained. A sketch edge map ...

In order to reduce the over segmentation of the traditional watershed algorithm,the algorithm was modified based on mathematical morphology and region merging.First,obtained gradient image by the multi-scale morphological method.Employed opening operation and closing operation of reconstruction to the gradie...
Region merging using homogeneity and edge integrity for watershed-based image segmentation A new joint region-merging criterion for watershed-based image segmentation is proposed. The proposed method combines, in a weighted fashion, criteria base... Hernandez,E Sergio - 《Optical Engineering》 被引量...
Image segmentation remains a challenging problem for object-based image analysis. In this paper, a hybrid region merging (HRM) method is proposed to segment high-resolution remote sensing images. HRM integrates the advantages of global-oriented and local-oriented region merging strategies into a unifi...
