Various scanning algorithms have been proposed to enhance the performance of intra prediction of H.264 codec. In this paper, an adaptive scanning scheme is proposed to achieve the entropy coding gain in intra coding, where scanning patterns are updated based on the probabilistic distribution of quantized coefficients of previous macroblocks so that the consecutive zeros are located at the rear ...

The discrete wavelet transform (DWT) has been widely used in scalable video coding for its advantages in multi-resolution analysis and subband decomposition. In this paper, a spatially scalable video coding system based on H.264 coding method and in-band overcomplete discrete wavelet transform (ODWT) technique is proposed, which integrates the good compression performance of H.264 in low freque...

A theoretical analysis of the overall mean squared error (MSE) in hybrid video coding is presented for the case of error prone transmission. The derived model for interframe error propagation includes the eeects of INTRA coding and spatial loop ltering and corresponds to simulation results very accurately. For a given target bit rate, only four parameters are necessary to describe the overall d...

A compressed video bitstream can be partitioned according to the coding priority of the data, allowing prioritized wireless communication or selective dropping in a congested channel. Known as data partitioning in the H.264/Advanced Video Coding (AVC) codec, this paper introduces a further sub-partition of one of the H.264/AVC codec’s three data-partitions. Results show a 5 dB improvement in Pe...

In this paper, we present an evaluation of various wavelet filters in the context of a JPEG 2000 based inter frame video coding system both on software and on hardware side. The software system itself is based on coding of a combination of intra frames and/or differential frames. Motion indicators are introduced and performed on the differential frames to determine the motion content (high or l...

The transmission errors in H.264 may propagate in the temporal direction. Errors in intra-coded picture (I-frame) will propagate into the associated P-B frame if they are in the same Group Of Picture (GOP). Therefore it is important to detect errors in the I-frame rather than in the P-B frame. This paper proposes and demonstrates an effective technique of Error-Resilient Coding based on bit-err...

In this paper, a novel embedded wavelet image compression algorithm, NEFZW (Novel Embedded Full Zerotree Wavelet) algorithm is proposed. The relationship of the intra scale subbands is exposed by the statistical experiments on various test images. Since “zerotree” indicates specially the inter scale relationship in EZW, the concept of full zerotree is proposed which includes both the relationsh...
