INTRODUCTIONTOMATLAB

Its name is derived from MATrixLABoratory.

Matlab is a program for doingnumerical computation.It was originally designed for solving

linear algebra type problems using

matrices.

A high-level technical computinglanguage and interactive environment

for algorithm development, data

visualization, data analysis, and

numeric computation.

Technical computing problems can besolved faster than with traditional

programming languages.

RELATIONSHIP BETWEEN MATLAB AND

IMAGE PROCESSING

The Image Processing Toolbox is a collection of

functions that extend the capability of the MATLAB

numeric computing environment.

The toolbox supports a wide range of image processing

operations, including :

Image enhancement

y Intensity of colours in imagey Deblurringy

Compressed images can be processed

y filtering and filter designy File formats:tiff,gif,bmp,png,hdf,pcx

y All the problems are solved by using matrices
