The basics of digital image processing are broadly classified into three major categories as Low-level image-processing includes Reduce Noise, Contrast Enhancement, Image Sharpening; Middle-level processing
consist of segmentation, Object Recognition, Classification, and High-level image processing covers &#39; Making Sense of an Ensemble of Recognized Objects i.e. Scene Understanding&#39;. These three levels of image processing require the relationship between pixels. This video channel focused on all three ways to measure the distance
between two pixels. It also illustrated three ways to define the neighboring and adjacency between pixels. There is always seems to be ambiguity about 8-adjacency and m-adjacency. The last few frames of the video
differentiate between 8-adjacent and m-adjacency by taking suitable examples. It not only explained that m- adjacency is a special case of 8-adjacency but also resolves the ambiguities in 8-adjacency.
