Please read full text as am working on the image processing feature extraction using region props and i get result in pixels and want to convert these pixel data into mm or cm . I need some calibration factor as i read comments here but for that i need cal_factor=(mm/pixelsize). here how can i get mm for calibration factor ? any suggestion please. my image resolution is 512x512, and pixel spacing is 0.9770, 0.9770. Help me to convert it to mm.
