Motion estimation and compensation is an essential part of existing video coding systems. The mesh-based motion estimation (MME) produces smoother motion field, better subjective quality (free from blocking artifacts), and higher peak signal-to-noise ratio (PSNR) in many cases, especially at low bitrate video communications, compared to the conventional block matching algorithm (BMA). Howev...

This paper discusses robust coding of visual content for a distributed multimedia system. The system encodes independently two correlated video signals and reconstructs them jointly at a central decoder. The video signals are captured from a dynamic scene, where each signal is robustly coded by amotion-compensatedHaar wavelet. The efficiency of the decoder is improved by a disparity analysis of...

There has been significant advances in the field of image and video processing over past few decades. The term "image processing" is used to describe multiple signal-processing methodologies where images (such as or picture frames) serves input, resulting another a collection image-related parameters features. majority include reducing two-dimensional signal it same way any other signal. "video...

NTSC composite color video is currently one of the most common formats of video broadcasting. Although the signal is analog, it can be decoded almost entirely digitally. Analog decoders offer limited video quality and require adjustments. Using digital techniques to implement NTSC decoding offers minimum adjustments and excellent video quality. This project presents the building blocks of digit...

Currently, the development of multimedia communication has progressed so rapidly that the video program service has become a requirement for ordinary customers. The quality of experience (QoE) for the visual signal is of the fundamental importance for numerous image and video processing applications, where the goal of video quality assessment (VQA) is to automatically measure the quality of the...

This paper presents a novel approach to dynamic transmission bandwidth allocation for transport of real-time variable-bit-rate video in ATM networks. Video traac statistics are measured in the frequency domain: the low frequency signal captures the slow time-variation of consecutive scene changes while the high frequency signal exhibits the feature of strong frame autocorrelation. Our queueing ...

The file size and picture quality are factors to be considered for streaming, storage and transmitting videos over networks. This work compares Cinepak, Intel, Microsoft Video and Indeo Codec for video compression. The peak signal to noise ratio is used to compare the quality of such video compressed using AVI codecs. The most widely used objective measurement by developers of video processing ...

Video fingerprinting is a newer research area. It is also called “content-based video copy detection” or “content-based video identification” in literature. The goal is to locate videos with segments substantially identical to segments of a query video while tolerating common artifacts in video processing. Its value as a tool to curb piracy and legally monetize contents becomes more and more ap...

In this paper, an integrated system model of MPEG-2 video compression/decompression system and OFDM transceiver system has been designed and implemented to investigate and study the impact of various parameters on the quality of the transmitted video signal. MPEG-2 codec system has been used to compress the original video signal to present it in a compressed form. OFDM modulation technique has ...
