An improved ezw algorithm based on set partitioning in hierarchical trees using wavelet regularity
2004 International Conference on Image Processing, 2004. ICIP '04., 2005This paper presents an improved embedded zerotree wavelet (EZW) coding algorithm, which makes use of the wavelet regularity to derive a classification criterion of wavelet coefficients in spatial-orientation hierarchical trees. Variations of the EZW algorithm discussed in the open literature have proposed some modifications in the process of exploiting

Modern automated microscopic imaging techniques such as high-content screening (HCS), high-throughput screening, 4D imaging, and multispectral imaging are capable of producing hundreds to thousands of images per experiment. For quick retrieval, fast transmission, and storage economy, these images should be saved in a compressed format.

Signal compression has been characterized as the removal of redundancy and irrelevancy. Fractional Fourier Transform (FRFT), an orthogonal, linear transform, is known to decompose the signal in terms of chirps. In this paper we propose a scheme for signal compression based on the combination of discrete FRFT (DFRFT) and set partitioning in hierarchical

Biomedical signals enfold much crucial clinical information. Cardiac imperfection includes information on the morphology of its electrical signals. These signals are classically recorded over a considerable period, so the size of data file becomes bulky and hence compression is essential.

The SPIHT (set partitioning in hierarchical trees) algorithm by Said and Pearlman (see IEEE Trans. on Circuits and Systems for Video Technology, no.6, p.243-250, 1996) is known to have produced some of the best results in still image coding. It is a fully embedded wavelet coding algorithm with precise rate control and low complexity.

Recent developments in medicine lead to enhance the provision of the healthcare services. In some medical areas, such as telesurgery, telediagnosis, and telemedicine, real-time analysis of patient’s vital biosignals (such as ECG signals from different leads, blood pressure and SpO2 waveforms) is necessary to support the patient and diagnose one’s ...
