Hello
I have been able to extract ROIs from contour, but if i count the no of pixels it also includes pixels which are not fully covered in the contour.. hence for my set of images i have evolving contours.. but pixel count does not change because of this. Is there is way i can account for the pixel fraction covered in contour.. and take that information for my ROI area calculation..?
I don't wish to use 'perimeter area' since perspective correction is to be applied in the area calculation..using distance of pixels from the center of image.
Can i 'extract ROIs' too with sub-pixel information..?
