Region Based Satellite Image Segmentation Using JSEG Algorithm

Image segmentation is a major research area due to its extensive usage and application in the area of computer vision. It is the basis of Image analysis and understanding. Satellite Image segmentation is a challenging and tough task due to the inherent nature of the image. A wide variety of various segmentation techniques for colour satellite images have been developed. Here, we come up with an approach called JSEG, "JPEG image segmentation" along with region growing to perform segmentation of satellite images. At first colour quantization is done to represent various regions in the image. Then a class map of that image is formed by replacing the image pixel colors by their corresponding color class labels. Applying this to local windows, results in ―J-image‖. Finally Region growing method is used to segment based on the multi-scale Jimages.
