computer vision 里有个著名的 SIFT algorithm. 具体这个算法 bro 就不赘述了. it's such a telling example of showing off what computers are good at, how it differs from humans, and how it accomplishes superhuman performance. a similar example is the audio search algorithm used in music recogniti...
Compared with the original SIFT algorithm, the proposed algorithm reduced the computational amount by 90 % and memory usage by 95 %. The final implementation used 58K gate count for UMC 90-nm CMOS technology, and offered 6000 feature points per frame for VGA size image at 30 frames per ...

In recent years, GPU received considerable attentions with its powerful parallel processing ability. Parallel computing on GPUs has been applied in many science and engineering applications successfully. In this research, we intend to use GPU to accelerate SIFT algorithm. The program will use linear ...
