No. As of now, No support from OpenCV for face recognition on GPU. By the way, You can detect face regions in images on GPU using OpenCV's GPU module. GPU version of cascade classifier is available. You will need to go further by yourself.

2014-02-16 23:46:16 -0500 asked a question data type conversion - GpuMat

I have Continuous GpuMat of size (10304,10304) and, of CV_8UC1 format at global memory of device. Now I want to pass that GpuMat to one function which requires a "float array on device". I have no idea what the efficient way is to do that conversion. any suggestion?
