I would like to delineate the patches automatically. The image is of a desert environment with small bush patches on sand dunes. So far I tried "imageSegmenter" in matlab, "image segmentation" and "FLS image segmentation" in ERDAS, and "Segmentation Image" in Envi (which worked best out of all). However, I'm still not completely satisfied with the results I'm getting. Anyone have experience with something similar?
Could you please show an example of your image? Is your goal to automatically extract those bush patches from the image? It would be also good if you can manually create an example of a segmentation result that can completely satisfy you.
You might try using eCognition if you have access to it. I know it is an expensive software. Here is a link: http://www.ecognition.com/ It is designed for object-based image analysis. We've used it to identify landscape-level soil features, but others have used it to identify vegetation patches or even individual shrubs.
Lars, while I don't have a stero-pair, the reference you provided looks very helpful. thanks!
