Detecting edges in an image

Edge detection is the most fundamental way of processing in computer vision to find features in an image based on the change in brightness and image intensity. A change in brightness results from discontinuity in depth, orientation, illumination, or corners. The edge detection method can be based on the first or second order:

The following graph illustrates the edge detection mechanism graphically:

Here, you can see that the intensity of the image changes from dark to bright around the midway point, so the edge of ...
