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 ...
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 ...
Wavelet image coding using the spherical representation
(IEEE, 2005)
In this paper, we introduce the "spherical representation", which provides a new adaptive framework for modeling and coding the image information in wavelet subbands. Based on this representation, a practical coding algorithm ...
Compression of the CT images using classified energy and pattern blocks
(IEEE, 2013)
In this work, a new biomedical image compression method is proposed based on the classified energy and pattern blocks (CEPB). CEPB based compression method is specifically applied on the Computed Tomography (CT) images and ...
Decoder side true motion estimation for very low bitrate b-frame coding
(IEEE, 2011)
In H.264 standard, coding of motion vectors constitutes a significant portion of total bitrate especially at low bitrate regimes. This is because differential coding of motion vectors is inefficient when the bit budget is ...
H.264 standardı için süper-çözünürlük tabanlı kodlama yaklaşımı
(IEEE, 2013-04-26)
Kodçözücü tarafında süper-çözünürlük (SC) uygulayarak H.264 standardının video kodlama verimliliğinin iyileştirilmesi literatürde ele alınmıştır. Bu bildiride farklı olarak, SC¸ kestirimi kodlama sırasında H.264 standardının ...
Kodlayıcı destekli video çerçeve hız artırımı
(IEEE, 2011)
Videoda çerçeve hız artırımı (ÇHA), devinim denkleştirme yöntemlerinin kullanılmasıyla hareketlerin daha keskin ve sürekli gösterimini sağlayarak görsel kaliteyi artırmaktadır. Fakat, devinim kestiriminde karşılaşılan ...
Wavelet-based image compression by hierarchical quantization indexing
(IEEE, 2009)
In this paper, we introduce the quantization index hierarchy, which is used for efficient coding of quantized wavelet coefficients. A hierarchical classification map is defined in each wavelet subband, which describes the ...
