# Identifying geometry in images

There is a lot of information on the internet about image classification and object identification. I want to know how I can extract (or create) geometric information from an image.

For example, if the image classifier can identify that there is a sphere in the image, how can i generate 3d vertices's and edges from that knowledge?

I want to find all the edges and points on these shapes

• I don't know why you require an ML algorithm for this task...at-least in the pics given the intensity and colour change is sudden, so simple program would do the job – DuttaA Mar 13 '18 at 10:15
