CALCULATION OF LUMINANCE FOR DATA-HIDING AND IMAGE COMPRESSION
Main Article Content
Abstract
There are many digital multimedia transmissions on the network. Therefore to protect the secret messages during transmission becomes an important issue. To guarantee communication efficiency and save network bandwidth compression techniques can be implemented to reduce redundancy and the quality of the decompressed versions should also be preserved. The proposed system is a joint data hiding and compression scheme the system helps to avoid the risk of the attack from interceptors and increase the implementation efficiency .The proposed joint data hiding and compression is based on SMVQ (side match vector quantization) and image inpainting.
