Answer 1

Answer:

When processing an image, we are often interested in identifying objects represented within it so that we can perform some further analysis of these objects e.g. by counting them, measuring their sizes, etc. An important concept associated with the identification of objects in an image is that of edges: the lines that represent a transition from one group of similar pixels in the image to another different group. One example of an edge is the pixels that represent the boundaries of an object in an image, where the background of the image ends and the object begins.
