A novel ordered-SPIHT for embedded color image coding
International Conference on Neural Networks and Signal Processing, 2003. Proceedings of the 2003
The magnitude distribution law of DWT coefficients of color image data in Karhunen-Loeve space is investigated. Considering the KLT matrix formed, the magnitude of DWT coefficients in components K , and , in general, have the relation K > > where , , are the three components of a color image in KL space. Based on this characteristic and other DWT coefficient features, a novel ordered-SPIHT for embedded color image coding (OCSPIHT) is proposed in this paper.
