Image segmentation is a preliminary and critical step in segment-based image analysis. Its proper evaluation ensures that the best segmentation result is used in image classification. In this paper, i...
COLOR IMAGE SEGMENTATION USING THE DEMPSTER-SHAFER THEORY OF EVIDENCE FOR THE FUSION OF TEXTURE
Color Texture Segmentation Theory of evidence
2015/5/18
We present a new method for the segmentation of color images for extracting information from terrestrial, aerial or satellite images.
It is a supervised method for solving a part of the automatic ext...
NEAR SET INDEX IN AN OBJECTIVE IMAGE SEGMENTATION EVALUATION FRAMEWORK
Automation comparison image information content nearness
2015/11/16
The problem considered in this article∗
is how to evaluate image segmentations objectively. An image segmentation is the partition of an
image into its constituent parts. Until recently, the e...
