Hi, I have a binary image with blobs being segmented. I have used the regionprops function to find the centroid, major axis,minor axis length, and orientation of the blobs. i need to draw the ellipse on these blobs. Any suggestion how to do it? Is there any inbuilt MATLAB function which does so? Also,i need that all my 10 blobs should be of different colors.
Thanks

It doesn't seem to allow arbitrary ellipse orientations. Or at least, I'm not finding a way to tilt it interactively.
