GPU Convolutions: OpenCV GPU and LibJacket – Part 2

This is a response to my earlier post comparing OpenCV's gpu::convolve() and LibJacket's jkt::conv2() convolution functions, at various image and kernel sizes. That post generated a lot of traffic, most notably from the OpenCV developer community. Taking note of this, it seems that the folks at Willow Garage have re-vamped their GPU convolutions and posted their own set of benchmarks using their updated routines. While the benchmarks I ran highlighted some performance issues in OpenCV - which the Read more [...]
