Didactic System for Video Compression

The video compression, due to its broad use, has raised the interest around it, by a large sector of the people. This work was born in this context, to develop a system that allows a contact with the concepts and more usual technique of the video compression system.

Statistical Multiplexing of H.264 video streams using Structural Similarity Inf...

In this paper, we propose a method to broadcast digital video programs in which the channel capacity is dynamically distributed among video programs according to each video program particular complexity. A bit rate control algorithm based on the Structural Similarity Index as the measure of video program complexity is examined. Initial results show that a uniform picture quality among video programs can be obta...

Coding of Multiple H.264 Video streams using SSIM as quality metric

This paper proposes a joint rate control scheme for multiple video sequences coding based on H.264/AVC standard that produces uniform picture quality. Structural Similarly Information (SSIM), is assessed as a coding complexity of a video program measure regarding its perceptual quality. Initial results are presented and discussed.

Statistical Multiplexing of H.264 programms

The advent of H.264/AVC is going to change the way Digital Television programs are broadcast. Each program can be independently encoded or jointly encoded resulting thus in a more efficient way to distribute the available channel bandwidth. This paper presents a combined coding scheme for multi-program video transmission in which the channel capacity is distributed among the programs according to the program co...

Object-based spatial segmentation of video guided by depth and motion information

Generic Framework for Video Analysis

In this paper we propose a framework for development of video analysis and description systems, in an easy and interactive way. Due to the architecture design the developed software can run on different operating systems and on distributed environments.
