Low-complexity block-based motion estimation via one-bit transforms

We present an algorithm and a hardware architecture for block-based motion estimation that involves transforming video sequences from a multibit to a one-bit/pixel representation and then applying conventional motion estimation search strategies. This results in substantial reductions in arithmetic and hardware complexity and reduced power consumption, while maintaining good compression perform...

Low complexity bit-plane entropy coding for 3-D DWT based video compression

This paper is dedicated to entropy coding for scalable video compression based on three-dimensional discrete wavelet transform (3-D DWT). A new simple bit-plane entropy coding of wavelet subband matrices is proposed. Practical results show that 3-D DWT video codec with proposed entropy coding allows to increase the encoding speed 2-3 times for the same quality level in comparison with x.264 cod...

A Low Complexity Prioritized Bit-plane Coding for SNR Scalability in MPEG-21 Scalable Video Coding

In this paper, we propose a low complexity prioritized bit-plane coding scheme to improve the rate-distortion performance of cyclical block coding in MPEG-21 scalable video coding. Specifically, we use a block priority assignment algorithm to firstly transmit the symbols and the blocks with potentially better rate-distortion performance. Different blocks are allowed to be coded unequally in a c...

Adaptive search area for fast motion estimation

In this paper a new method for determining the search area for motion estimation algorithm based on block matching is suggested. In the proposed method the search area is adaptively found for each block of a frame. This search area is similar to that of the full search (FS) algorithm but smaller for most blocks of a frame. Therefore, the proposed algorithm is analogous to FS in terms of reg...

cient Motion Vector Estimation and Coding for H . 263 - Based Very Low Bit Rate Video Compression

In this paper, we propose an e cient motion vector estimation and coding method for H.263-based low bit rate video compression. The method exploits structural constraints within the motion eld. The same H.263 median predictor is used to localize motion estimation, which is directed to the best motion vectors by employing a computation-constrained layered search technique. Moreover, the localize...
