Sometimes the image may be so blurred to see.In particular case we can use image processing field to process the image and we can view clear image.

We can adjust the color contrast  of the image.In medical field it is very useful.For example: finding tumor in particular organs.It detects the tumor presents in the organ.We will see how it detects the particular objects in the following tutorial.

Image processing-an introduction

Image processing:We have to process a raw image.you can see the original image below

It has no of pixels,which you can see the result below.Each pixel has 8 bit,ranging from 0-255.

 Generally an image is defined as a two-dimensional function,f(x,y),where x,y are intensity values.depends up on image size we get the intensity values.each color image has RGB(red,green,blue)components.intensity values are nothing but rgb values,ranging from 0-255.If it is red component it displays some values.likewise if it is a green component it displays the values which belongs to green and so.
