.Digital image is composed of finite number of elements
Elements – Picture Elements, Image Elements, Pels or Pixels
.Pixel is used to denote the elements of a digital image
.A digital image is a mapping from the real three-dimensional world to a set of two-dimensional discrete points. Each of these spatially distinct points, holds a number that denotes grey level or colour for it, and can be conveniently fed to a digital computer for processing.
Digital Image Processing deals with images which are two-dimensional entities (such as scanned office documents, x-ray films, satellite pictures, etc) captured electronically through a scanner or camera system that digitises the spatially continuous coordinates to a sequence of 0’s and 1’s.
Introduction to MAT LAB
MATLAB stands for matrix laboratory.
MATLAB is a high-performance language for technical computing.
It integrates computation, visualization, and programming in an easy-to-use environment.
Digital Image Processing using MATLAB is very ‘interactive’ ,allows formulating solutions to many technical problems ,those involving Matrix Representations in fraction of time .
