The main reasons for compression in multimedia systems are: (1) large storage requirements of multimedia data, (2) relatively slow storage devices which do not allow playing back uncompressed multimedia data in real time, and (3) the network bandwidth which does not allow real-time video data ...
In this paper, a wavelet-based multimodal compression method is proposed. The method jointly compresses a medical image and an ECG signal within a single codec, i.e., JPEG-2000 in an effective and simple way. The multimodal scheme operates in two main stages: the first stage, consists of...

In contrast, MPEG (Moving Picture Experts Group) refers to a set of standards used for compressing audio and video files. MPEG compression enables the efficient transmission of multimedia over bandwidth-limited networks, ensuring that movies and music are easily streamed and downloaded. 10 While ...
This "transcompression" method has many applications for the Internet and multimedia networks. Since most "original" images or video files stored on computers around the world are in JPEG or MPEG formats, our algorithm provides a simple and efficient way to redistribute pictures/video files across...
The recent explosion in multimedia and networking application places a great demand on efficient transmission of images at low bit rate with high security. Mixing several existing standard encryption techniques with image encoding tends to change the compression ratio greatly. In this paper, a novel ...
Steganography is art of hiding a secret media in another media. One of the major challenges in steganography is robustness, since the stego-signal need to survive multiple kinds of data processing. Low pass filtering, for example JPEG compression, is known as a common attack against stego-signal...
