I'm extracting image statistics using ROI as spatial subset and i would like to know more about the rules regarding the inclusing/exclusion of a given pixel. Is it based on the pixel area included in the AOI or the position of the pixel center? For ex.: * If 50% of pixel area is included within the AOI, then pixel is considered in the statitics * If the gravity center of pixel is included within the AOI, then pixel is considered in the statitics Thanks in advance
