Hello Ray,

Hope you are doing good!

I need your help! I am trying to create a mask from a UIImage for matching algorithm. I tried CIFilters also but result is not so satisfactory. Please guide me with a correct approach.

For example, i have an image of Eagle in jpg format , what i want to do is to outline the eagle in that image and fill it with black color, and white color for background.

Regards.
