Rate Distortion Analysis and Bit Allocation Scheme for Wavelet Lifting-Based Multiview Image Coding [PDF]
, 2009 This paper studies the distortion and the model-based bit allocation scheme of wavelet lifting-based multiview image coding. Redundancies among image views are removed by disparity-compensated wavelet lifting (DCWL).

Stack-run adaptive wavelet image compression [PDF]
, 2003 We report on the development of an adaptive wavelet image coder based on stack-run representation of the quantized coefficients. The coder works by selecting an optimal wavelet packet basis for the given image and encoding the quantization indices for ...

Minimum Distortion Variance Concatenated Block Codes for Embedded Source Transmission
, 2014 Some state-of-art multimedia source encoders produce embedded source bit streams that upon the reliable reception of only a fraction of the total bit stream, the decoder is able reconstruct the source up to a basic quality.

Design of Biorthogonal Wavelets based on Spline and Spline-like Functions for Image Compression
International Journal of Emerging Research in Engineering, Science, and Management, 2022 Wavelet theory inspired from Fourier analysis is based on the basis function and its properties. Different wavelets use different basis functions which may better suit to some applications.

Adaptive two-step method for providing the desired visual quality for SPIHT
Радіоелектронні і комп'ютерні системи, 2022 Lossy compression has been widely used in various applications due to its variable compression ratio. However, distortions are introduced unavoidably, and this decreases the image quality.

Comparison of IRIS Image Compression using JPEG 2000, SPIHT and modified SPIHT algorithm
IOSR Journal of Electronics and Communication Engineering, 2014 Biometric recognition is a common and reliable way to authenticate the identity of the person. Iris recognition is an automated method of biometric identification that uses mathematical pattern-recognition techniques on images of the irides of an individual's eyes.

Evaluation of the Medical Image Compression using Wavelet Packet Transform and SPIHT Coding
International Journal of Electrical and Computer Engineering (IJECE), 2018 Wavelet transforms and wavelet packets are widely imposed in the analysis and resolution of problems related to science and technical engineering. Decomposition wavelet packet allows several frequency bands according to various levels of resolutions.

ROBUST IMAGE TRANSMISSION USING SPIHT AND TURBO- CODES
Electrica, 2008 This work describes a method for providing robustness to errors from a binary symmetric channel for the SPIHT image compression. The source rate and channel rate are jointly optimized by a stream of fixed-size channel packets.

Three-Dimensional SPIHT Coding of Volume Images with Random Access and Resolution Scalability
EURASIP Journal on Image and Video Processing, 2008 End users of large volume image datasets are often interested only in certain features that can be identified as quickly as possible. For hyperspectral data, these features could reside only in certain ranges of spectral bands and certain spatial areas ...
