Lossy compression schemes can be based on a source model, as in the case of speech compression, or a user or sink model, as is somewhat the case in image compression. In this chapter we look at audio ...

In MPEG Layer III coding the compression gain is mainly achieved through the unequal distribution of energy in the different frequency bands, the use of the psychoacoustic model, and Huffman coding.

Coding, information theory and compression constitute the backbone of modern digital communications and data storage. Grounded in Shannon’s seminal work, information theory quantifies the ...

Abstract: Point cloud compression is a technique that aims to address the challenge of storing and transmitting large-scale 3D data by reducing the size of point cloud data while maintaining ...

We are currently researching a video and audio coding technologies for advanced terrestrial broadcasting. Here, we present a real-time versatile video coding (VVC *) decoder that supports multilayer ...

This is the project which I did in my 4th semester as part of the Data Structures and Algorithms subject. In this project, I implemented the Huffman Coding Algorithm for file compression and ...

Abstract: In this paper we present a new joint encryption and compression coding scheme of natural images which is intended for the use in conjunction with a popular JPEG image compression standard.

Recent papers and codes related to deep learning/deep neural network based image compression and video coding framework. [Macau University] Yumo Zhang, Zhanchuan Cai , Senior Member, IEEE, and ...
