Hello everyone, 

In this project an Image Compression technique was implemented. This technique is a very popular one, Discrete Cosine Transform. When you search on google for DCT Image Compression you can easily find a source code for Grayscale images to implement DCT in Matlab, however it is  hard to find RGB Image Compression using DCT on the internet.




Therefore I wrote the code and am presenting it here for you:




In order to test the software I used a scenery photo with a file size of 4MB. Let's see what happens if we compress it by using %20 quality. This means the ratio is 5:1.

Original Image 4MB


After compression the file size is only 963 KB and image quality is nearly the same ! 



 Compressed Image 963 KB
