We present a comparative study of the efficiency and effectiveness of different implementation strategies for real-time video processing. In particular, we tested the performance of GPU processors (using the CUDA library) against the performance of quad-core PC Intel processors (using the Intel Performance Primitives library). The test consisted on applying a standard group of image processing algorithms, including histogram equalization, and convolution filtering, to a number of high definition video sequences and measuring the performance of each implementation. The results show that GPU processing is extremely cost-effective, but with the drawback that the underlying programming framework is very architecture-dependent, making it prone to the hardware idiosyncrasies, and therefore less abstract and reusable.
