Mobile Information Systems, Volume 2021, Issue 1, 2021., 2021 Lossy compression can produce false information, such as blockiness, noise, ringing, ghosting, aliasing, and blurring. This paper provides a comprehensive model for optical remote sensing image characteristics based on the block standard deviation’s retention rate (BSV).

Hyperspectral image compression : adapting SPIHT and EZW to Anisotropic 3-D Wavelet Coding [PDF]
, 2008 Hyperspectral images present some specific characteristics that should be used by an efficient compression system. In compression, wavelets have shown a good adaptability to a wide range of data, while being of reasonable complexity.

ROI coding of volumetric medical images with application to visualisation [PDF]
, 2003 This paper presents region of interest (ROI) coding of volumetric medical images with the region itself being three dimensional. An extension to 3D-SPIHT which allows 3D ROI coding is proposed.

SPIHT for generalized multiple description coding [PDF]
Proceedings 1999 International Conference on Image Processing (Cat. 99CH36348), 2003 We present a simple and efficient scheme for using the Set Partitioning in Hierarchical Trees (SPIHT) image compression algorithm in a generalized multiple description framework. To combat packet loss, controlled amounts of redundancy are added to the original data during the compression process.

THE PROBLEM OF CONTOURS IN TRANSFORM IMAGE CODING [PDF]
, 2008 Object contours contribute to a large extent to the perceived quality of an image but are typically quite hard to compress. As a matter of facts, many coding algorithms fail to describe efficiently this information.

Modified spiht algorithm for quincunx wavelet image coding [PDF]
, 2019 In this paper, an image compression method based on the Quincunx algorithm coupled with the modified SPIHT encoder (called SPIHT-Z) is presented. The SPIHT-Z encoder (coupled with quincunx transform) provides better compression results compared with two ...
