  • In my in my area of research, it's common for us to want to process about 100 images a second in order to get real time display. Each image has about a million elements in it. I 've got to process about a half a gig of data a second in order to get anything out of it.

    在我们的研究领域内,我们经常要在一秒钟内处理大概,100张图片以获得实时显示,每个图片大概包括了100万像素,因此我必须在1秒内,处理半个G的数据,来获取我想要的。
