I am writing an algorithm to calculate edge location on a equalized binary image (having pixels 0 & 255 and not 0 & 1) with subpixel accuracy. How come LabVIEW's edge detection vi is giving edge location in decimals ( for ex. 1234.12) on this equalized binary image? I understand that on grayscale image LabVIEW calculates edge location with subpixel accuracy using interpolation method on edge gradient profile along a search line. I am not able to understand the decimal edge location on a equalized binary image. Please help.
