Key differences between Core Image and GPUImage

Question

What are the major differences between the Core Image and GPUImage frameworks (besides GPUImage being open source)? At a glance their interfaces seem pretty similar... Appl

Answer 1

This is an old thread, but I think it's worth noting that GPUImage also has some features that are not present in Core Image: notably hough transform and several edge detection filters.

Core Image seems all about applying filters and effects — and it's good to see GPUImage explores more on image/video analysis, kind of becoming more like openCV, but in a more efficient way.
