GPUImage and OpenCV

edit

Hey ALl, So far I am loving OpenCV. It integrates well into my IOS app. In addition to OpenCV, I am using GPUImage. Have any of you used both libraries for processing the live preview from an IOS camera?

Currently I am thinking porting OpenCV's findContours to GPUImage is how to get my job done. On the other hand maybe porting GPUImage's GPUImageSobelEdgeDetectionFilter to OpenCV is the way to go.

If any of you have applied effects to live video I would love to see what you have done.
