2. objective
• The main objective of this project reduce channel
band width and increase security in communication
networks

3. Abstract
• In this project we propose a data hiding and
compression scheme based on SMVQ and image in
painting.
• In this the function of data hiding and image
compression can be integrated into one single
module.
• The proposed scheme shows the performances for
compression ratio and better peak signal to noise
ratio.

4. Introduction
 With the rapid development of internet technology, people can
transmit and share digital content with each other
conveniently.
 In order to guarantee communication efficiency and save
network band width, compression technique can be
implemented on digital contents to reduce redundancy, and
the quality of the decompressed versions should also be
preserved.
 Now a days, most digital content, especially digital images and
videos, are converted into the compressed forms for
transmission.

5. Existing method
• In existing method vector quantization is provide
low peak signal to noise ratio and time complexity.

6. disadvantages
• Low image quality
• Information hiding survey is required high
bandwidth
• It give low PSNR

7. Proposed system
• In this we propose a novel joint data hiding and
image compression based on SMVQ and image in
painting.

8. Advantages
• Hiding capacity.
• Compression ratio.
• Reduce redundancy, and
• The quality of the decompressed versions
should also be preserved

9. Applications
• Save network bandwidth.
• It used in transmit and share digital contents
without loss of information.
• Transmit secret or private data securely
