Classification-based macroblock layer rate control for low delay transmission of H.263 video
(IS & T - Soc Imaging Science Technology, 2003-07)
Puri and Aravind's method of macroblock bit count estimation for video rate control is based on the classification of the macroblock data into discrete classes and assigning a unique non-linear estimate for each class and ...

Spherical coding algorithm for wavelet image compression
(IEEE-Inst Electrical Electronics Engineers Inc, 2009-05)
In recent literature, there exist many high-performance wavelet coders that use different spatially adaptive coding techniques in order to exploit the spatial energy compaction property of the wavelet transform. Two crucial ...
A novel image compression method based on classified energy and pattern building blocks
(Springer International Publishing AG, 2011)
In this paper, a novel image compression method based on generation of the so-called classified energy and pattern blocks (CEPB) is introduced and evaluation results are presented. The CEPB is constructed using the training ...
H.264 video kodlamada çerçeve seviyesinde karmaşıklık kontrolü
(IEEE, 2007)
H.264 kodlama standardı, değişken blok boyutlu makroblok bölüntüleri kullanan çok sayıda farklı çerçeveler arası kestirim kipini desteklemektedir. Ne var ki, her olası bölüntü için eniyi devinim vektörlerini aramanın ...
Rate-distortion and complexity joint optimization for fast motion estimation in H.264 video coding
(IEEE, 2006)
H.264 video coding standard offers several coding modes including inter-prediction modes that use macroblock partitions with variable block sizes. Choosing a rate-distortion optimal mode among these possibilities contributes ...
Fast inter-mode decision and selective quarter-pel refinement in H.264 video coding
(IEEE, 2008)
In H.264 video coding standard, there exist several inter - prediction modes that use macroblock partitions with variable block sizes. Choosing a rate-distortion optimal coding mode for each macroblock is essential for the ...
Postprocessing of decoded color images by adaptive linear filtering
(Elsevier Science, 2003-02)
This paper presents an image adaptive linear filtering method for the reconstruction of the RGB (red, blue, green) color coordinates of a pixel from the lossy compressed luminance/chrominance color coordinates. In the ...
Predictive vector quantization of 3-D mesh geometry by representation of vertices in local coordinate systems
(Elsevier Inc, 2007-08)
In predictive 3-D mesh geometry coding, the position of each vertex is predicted from the previously coded neighboring vertices and the resultant prediction error vectors are coded. In this work, the prediction error vectors ...
Significance map pruning and other enhancements to SPIHT image coding algorithm
(Elsevier Science, 2003-10)
This paper proposes several enhancements to the Set Partitioning in Hierarchical Trees (SPIHT) image coding algorithm without changing the original algorithm's general skeleton. First and foremost, a method for significance ...
