I have a series of images which I need to find the x,y coordinates for a single white blob on black background. I would like coordinates to be taken from the center of the image. Thank you.
This is done by my BlobsDemo program. http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862.
The blobs are the coins from the standard MATLAB demo image. It finds the centroids of all of them. You just need to subtract the number of rows and columns divided by 2 to get the coordinates referenced to a new coordinate system where the origin is in the middle of the picture.
