Internet data almost double every year. The need of multimedia communication is less storage space and fast transmission. So, the large volume of video data has become the reason for video compression. The aim of this paper is to achieve temporal compression for three-dimensional (3D) videos using motion estimation-compensation and wavelets. Instead of performing a two-dimensional (2D) motion s...

Video signals differ from image signals in several important characteristics. Of course the most important difference is that video signals have a camera frame rate of anywhere from 15 to 60 frames/s, which provides the illusion of smooth motion in the displayed signal. Another difference between images and video is the ability to exploit temporal redundancy as well as spatial redundancy in des...

In this talk we will describe embedded image and video compression techniques. We describe an embedded zero tree-like approach that exploits the interdependency between color components that is known as Color Embedded Zero Tree Wavelet (CEZW). We will also present a video compression technique, Scalable Adaptive Motion Compensated Wavelet (SAMCoW) compression, that uses the CEZW data structure ...

In this paper, we consider the problem of lossless compression of video by taking into account temporal information. Video lossless compression is an interesting possibility in the line of production and distribution. We propose a compression technique which is based on motion compensation, optimal 3D linear prediction and context based GolombRice entropy coding. The proposed technique is compa...

In transmitting image/video data over Video Sensor Networks (VSNs), energy consumption must be minimized while maintaining high image/video quality. Although image/video compression is well known for its efficiency and usefulness in VSNs, the excessive costs associated with encoding computation and complexity still hinder its adoption for practical use. However, it is anticipated that high-perf...

Traditional image and video compression algorithms rely on hand-crafted encoder/decoder pairs (codecs) that lack adaptability and are agnostic to the data being compressed. Here we describe the concept of generative compression, the compression of data using generative models, and suggest that it is a direction worth pursuing to produce more accurate and visually pleasing reconstructions at muc...

Real-time video communication over the internet and other heterogeneous IP networks has become a significant part of modern communications, underlining the need for highly effi‐ cient video coding algorithms. The most desirable characteristic of such an algorithm would be the ability to maintain satisfactory visual quality while achieving good compression. Ad‐ ditional advantageous characterist...

It is expected that video streaming services will play an important role in 4G wireless systems. Since video communication has typically large and varying bandwidth requirements, high spectrum utilization techniques are needed to support high quality video. In this paper we propose a combination of Cooperative Header Compression (COHC) method with Multiple Description Coding (MDC), which introd...
