以下答复杜绝机译,请予以关注。Edges characterize boundaries and are therefore a problem of fundamental importance in image processing. 边缘表征边界,而且因此在图像处理中成为一个具有根本重要性的问题。Edges in images are areas with strong intensity contrasts ,a jump in intensity from one pixel to the next.图像中的边界是具有强烈光强反差的区域,即光强从一个像素到下一个像素的跳跃。 Edge detecting an image significantly reduces the amount of data and filters out useless information, while preserving the important structural properties in an image. 边缘检测一个图像大大减少了数据量,而且滤除了无用的信息,同时则保留了图像中重要的结构性质。This was also stated in my Sobel and Laplace edge detection tutorial, but I just wanted reemphasize the point of why you would want to detect edges.这在我的Sobel和Laplace边缘检测论文中也做了说明,但是我只想再次强调一点,就是我为什么要检测边缘。
