چکیده

A compression scheme is presented that has been designed to e ciently code light elds. Based on video compression techniques, the light eld image array is divided into image blocks. Di erent block-coding modes have been devised to exploit redundancy between images over a wide range of target bit rates. Prediction from multiple reference images further enhance coding e ciency. Rate-constrained mode selection is accomplished by employing Lagrangian optimization. The coder's operational ratedistortion performance is evaluated using di erent light elds. Depending on lighteld scene characteristics and reconstruction quality, compression ratios up to 1000:1 are achieved.

New adaptive interpolation schemes for efficient meshbased motion estimation

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...

Power Allocation Strategies in Block-Fading Two-Way Relay Networks

This paper aims at investigating the superiority of power allocation strategies, based on calculus of variations in a point-to-point two-way relay-assisted channel incorporating the amplify and forward strategy. Single and multilayer coding strategies for two cases of having and not having the channel state information (CSI) at the transmitters are studied, respectively. Using the notion of cal...

Perceptual adaptive JPEG coding

An extension to the JPEG standard (ISO/IEC DIS 10918-3) allows spatial adaptive coding of still images. As with baseline JPEG coding, one quantization matrix applies to an entire image channel, but in addition the user may specify a multiplier for each 8x8 block, which multiplies the quantization matrix, yielding the new matrix for that block. WEG 1 and 2 use much the same scheme, except there ...

FPGA based High Performance CAVLC Implementation for H. 264 Video Coding

Context-based adaptive variable-length coding (CAVLC) is an important feature of the latest video coding standard H. 264/AVC. The coding technique using conventional CAVLC based on area efficient design, the second is on low power design architecture will lead to low throughput. In this paper, an efficient CAVLC design is proposed. The main concept is the FPGA based pipelining scheme for parall...

Improved Adaptive Block Truncation Coding for Image Compression

The Block Truncation Coding (BTC) is one of the lossy image compression algorithms. In this paper, we have proposed a method called the Improved Adaptive Block Truncation Coding (IABTC) based on Adaptive Block Truncation Coding (ABTC). The feature of inter-pixel redundancy is exploited to reduce the bit-rate further by retaining the quality of the reconstructed images. The proposed method outpe...
