I am a new user of OTB and I am really interested in OBIA classification. Until now I applied the segmentation procedure (using mean shift algorithm), and I would like to move forward with the classification.
I use an multispectral image (Sentinel 2A) with 40 bands. Each 10 bands correspond to 1 season.
So, I would like to ask how can I integrate radiometric indices (e.g.NDVI, SVI) in the TrainVectorClassifier application. Based on the documentation, ComputeImageStatistics is used to create an .xml file with statistics, and it is used in the training procedure.
Is it possible to add external info (NDVI) in these statistics? And how could I combine information of computed indices from different seasons.
Any suggestion would be helpful !!!
