An improved SPIHT algorithm for lossless image coding
Digital Signal Processing, 2009In this paper, we propose a new wavelet-based lossless image coder that is based on a state-of-the-art algorithm, namely SPIHT (set partitioning in hierarchical trees). An algorithmic modification is introduced in order to increase its efficiency. This consists of adding a new test on direct descendants in the sets of type A to process the parent ...

An Enhanced Compression Method for Medical Images Using SPIHT Encoder for Fog Computing
International Journal of Image and Graphics, 2023When it comes to filtering and compressing data before sending it to a cloud server, fog computing is a rummage sale. Fog computing enables an alternate method to reduce the complexity of medical image processing and steadily improve its dependability ...

Resolution scalable SPIHT (RS-SPIHT)
SPIE Proceedings, 2006A new embedded rate scalable and resolution scalable, lossless image compression technique based on Highly Scalable - Set Partitioning in Hierarchical Trees (HS-SPIHT) is developed. The new method, called Resolution Scalable-SPIHT (RS-SPIHT), encodes the regions in the next higher resolution that are most likely to be significant along with the current

2014 Tenth International Conference on Signal-Image Technology and Internet-Based Systems, 2014
An improved SPIHT algorithm that combines the SPIHT and the sub bands threshold calculation to reduce the number of comparison operations, without sacrificing the reconstructed image quality, is proposed. After applying discrete wavelet transform to the image, the threshold of each independent sub band is calculated.

Unsymmetrical SPIHT Codec and 1D SPIHT Codec
2010 International Conference on Electrical and Control Engineering, 2010Conventional SPIHT compression is for a 2D image or image block with the same maximum feasible decomposition level in two directions, so, only the size of image or image block is symmetrical, that is to say the maximum feasible decomposition level in two directions must be same and the image sizes had better be equal to 2level such as 32, 64, 128 etc ...
