Digital Image and video Processing

In an image compression system, 16384 bits are used to represent a 128×128 image with 256 gray levels. What is the compression ratio for this system?

_________  is the process of reconstruction of original scene from a degraded observation like noise

The reduction of the amount of data required to represent a digital image is known as

Description is otherwise Called as_______

In 4-neighbours of a pixel p, how far are each of the neighbours located from p?

Two regions are said to be ___________ if their union forms a connected set.

The distance between pixels p and q, the pixels have a distance less than or equal to some value of radius r centred at (x,y) is called

The distance between pixels p and q, the pixels have a distance less than or equal to some value of radius r, form a diamond centred at (x,y) is called

The formula for city block distance is

A pixel “ p” at coordinates (x, y) has neighbors whose coordinates are given by: (x+1, y+1),        (x+1, y-1), (x-1, y+1), (x-1, y-1). This set of pixels is called as A pixel “ p” at coordinates (x, y) has neighbors whose coordinates are given by: (x+1, y+1),        (x+1, y-1), (x-1, y+1), (x-1, y-1). This set of pixels is called as
