MATLAB code of Image compression and Encryption using DCT and AES respectively.

Hello, Guys posting one project in the field of digital image processing. The title of the project is Image compression and Encryption using DCT and AES respectively. The ides behind this project is first input uncompressed image is compressed using DCT compression method and then it is encrypted using AES encryption algorithm. At the receiver side first, it is decrypted using AES decryption and then it is decompressed using DCT.  The MATLAB implementation of the project is shown in the following YouTube video. just have a look.

YouTube Video of the Project: 


The implementation of the project is exactly as shown below. 
Sender side:
-- Take input Image
-- Apply DCT compression 
-- Apply AES Encryption
Receiver side:
-- Take encrypted data
-- Apply Decryption using AES
-- Apply DCT algorithm for decompression
