Scheduling latency insensitive computer vision tasks

In recent times, there are increasing numbers of computer vision and pattern recognition (CVPR) technologies being applied to real time video processing using single processor PCs. However, these multiple computational expensive tasks are generating bottlenecks in real-time processing. We propose a scheme to achieve both high throughput and accommodation to user-specified scheduling rules. The scheduler is then distributing 'slices' of the latency insensitive tasks such as video object recognition and facial localization among the latency sensitive ones. We show our proposed work in detail, and illustrating its application in a real-time e-learning streaming system. We also provide discussions into the scheduling implementations, where a novel concept using interleaved SIMD execution is discussed. The experiments have indicated successful scheduling results on a high end consumer grade PC. © Springer-Verlag Berlin Heidelberg 2005
