The goal of Vision-GPU is to achieve real time image and multimedia processing techniques using modern programmable Graphic Processing Units (GPU).
Real-time image processing on video frames is difficult to attain even with the most powerful modern CPUs. Increasing resolution of video capture devices and increased requirement for accuracy make it is harder to realize real-time performance. To address the high computational demands of video and multimedia data processing, Vision-GPU research explores the computational power from widely available, low-cost Graphics Processing Units (GPUs). We already demonstrated standard image and video analysis operations, such as convolution, edge detection, and motion tracking can have more than 10 times speedup on most of GPUs over single high-end CPUs. Our goal is to show the viability of applying GPUs to general image and multimedia processing, and provide optimization strategies for various vision processing operations using GPUs.
