How to calculate distance between center of white pixels in an image?
显示 更早的评论
In this iamge, I want to measure the distance between the center of area of white pixels marked below.
As these are not definite shapes, how do I find the center of these and then measure the distance in pixels between their centers.

REad about imdistline; this will allow you to calculate the distance between the points interactively. For this you are supposed to have image toolbox.
[y,x] = find(I==1) ; % give the pixel value
The above line, gives you the coordinates/ points of the required pixel. YOu have the points in hand, you can do the process needed.

You can get the center of image using mean.

You can find the center (centroid) of each white region using REGIONPROPS, and then just calculate the distance between the centers that regionprops returns.
