What is "Digital Image Processing".

          Here we are in the world of Digitalisation. Most of the photos we see are Digital. They are pictured with a Digital camera.

          As a technology, analog is the process of taking an audio or video signal and translating it into electronic pulses.Digital on the other hand is breaking the signal into a binary format where the audio or video data is represented by a series of "1"s and "0"s.

   
         Digital versus analog can refer to method of input, data storage and transfer, the internal working of an instrument, and the kind of display.
         Here we come to the main point which is Processing of a Digital image. A

 Digital Image contains information in forms of "0" and "1". By the use of computer algorithms we can perform processing."MAT-LAB" is a main way to process the Digital Images. We can show out each and every point of a Digital Image in the form of "X" and "Y". We can also figure out the colour composition of each  point in the basic three colours RED, GREEN and BLUE.

So how can we change the intensity of a point or part of image...?
With the help of MAT-LAB Tool boxes we can change the brightness and color content of a image. We can turn a colored image into a black and white image or a pure RED,GREEN or BLUE one.

Above two images are perfect example. In first one the color image has Green,Blue and Red component. While in second image ratio of colors are different.
