Hi mickael. I would like to perform this task (segmentation and class') & I have the pleiades pan-sharp image (4 bands)...
can you just direct me on: 1. Let me understand you input - when you say "begin by rasterize the shape file for all features in the shape file" - I understand that "features" are the segmentation shapes output from ,lets say, the Mean-Shift segmentation 2. if so, what do you mean by "You will get a set of images" - I get one segmentation shape file where all segments have only different DN names - so why or how I get set of images. please explain what each image represents ... 3. When you say "classify this image of objects with classical svm" - I understand that the raster segmented image should includes radiometric info' of each segment which is the input to the SVM Thanks in advanced...
