WebJul 13, 2010 · 1. Detection: The probability of detecting real edge points should be maximized while the probability of falsely detecting non-edge points should be minimized. This corresponds to maximizing the signal-to-noise ratio. 2. Localization: The detected edges should be as close as possible to the real edges. 3. WebThe AForge.Imaging.Filters namespace contains collection of interfaces and classes, which provide different image processing filters. Classes of this namespace allow to do different transformation of a source image, doing it directly on the source image or providing new image as a result of image processing routine.
