Digital Image Processing

 

·  Implemented various image processing algorithms such as color models, algebra operation,geometric transformations, enhancement (point, histogram, smooth, sharpen),frequency domain, degrade, restore.

Implemented color channel switch:

  BRG           GRB        RBG   

3.Grey Scale

Implemented 8 different algorithms for grey scale :

Middle one is original

4.Arithmetic (selected)

P1
P2
Divide (P1/P2)

‍

‍

Add (P1+P2)
Multiply (P1*P2)
Difference (|P1-P2|)

‍

5.Geometric

Ripple & Spherical & Twirl

6.Point

They are original, brightness, exponent, log, contrast and pow respectively.

7.Sharpen

3 Different Prewitt
3 Different Emboss
