İmge kodlaması için dalgacık paketlerinde küresel gösterim
(IEEE, 2008-09-26)Bu bildiride, dalgacık dönüşümü için geliştirdiğimiz küresel kodlama algoritmasının dalgacık paketlerine uyarlanması sunulmuştur. Bu kodlayıcıda yerel katsayı enerjisi, dalgacık altbantlarında varolan uzamsal bilgiyi ... -
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 ... -
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 ... -
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 ...
