A segmentation method based on texture gradient is proposed for the high resolution remote sensing images which have rich texture information. First, Nonsubsampled Contourlet Transform is used to extract texture features. Second, texture gradient is calculated, and then it is combined with the intensity gradient to get the final gradient. At last, the labeling watershed algorithm is used in segmentation...
In computer vision and pattern recognition, the role of image processing for image segmentation or object boundary recognition plays a key role. In traditional snake algorithm the boundary of image is considered as parametric curve. The process of finding an object boundary has become an energy minimization process. In the project work a combined process of GVF Snake algorithm which has larger capture...
