MATLAB code of Image Compression using JPEG

Hello, friends today I would like to post one more project in the field of digital image processing. The title of the project is image compression using JPEG (Joint photographic expert group). This project is implemented in matlab. 

The matlab implementation of the JPEG image compression standard is shown in the following YouTube video. Just have a look.  

Basically, JPEG compressed uses DCT for image transformation, After transformation of an image, the image is scanned using zigzag scanning. After scanning the Huffman encoding technique is used to encode the DCT coefficients.
