Setting priorities: a new SPIHT-compatible algorithm for image compression [PDF]
, 2000 We introduce a new algorithm for progressive or multiresolution image compression. The algorithm improves on the Set Partitioning in Hierarchical Trees (SPIHT) algorithm by replacing the SPIHT encoder.

Comparative Performance Evaluation of Three Image Compression Algorithms
Journal of Applied Science & Process Engineering, 2017 The advent of computer and internet has brought about massive change to the ways images are being managed. This revolution has resulted in changes in image processing and management as well as the huge space requirement for images’ uploading, downloading,

Contemporary Affirmation of SPIHT Improvements in Image Coding [PDF]
, 2013 Set partitioning in hierarchal trees (SPIHT) is actually a widely-used compression algorithm for wavelet altered images. On most algorithms developed, SPIHT algorithm from the time its introduction in 1996 for image compression has got lots of interest ...

[[alternative]]Using Hybrid Coders with SPIHT for Volumetric Medical Images
, 2013 [[abstract]]隨著科技的進步及發展，醫療影像數位化技術在醫療領域有相當程度的革新與發展，由於數位醫學造影設備越來越普遍，數位醫學影像也隨之急劇增加，使得所需的儲存空間呈爆炸性的成長，除了大幅增加PACS (picture archiving and communication system)系統的負擔之外，也大大的增加儲存設備的成本，因此醫學影像壓縮的工作就顯得格外重要。壓縮的原理是去除影像中的冗餘性來減少資料容量，以有效降低影像所佔之容量，因此，若能根據被壓縮資料本身的特性來修改壓縮流程 ...

Compressive Data Hiding: An Unconventional Approach for Improved Color Image Coding
EURASIP Journal on Advances in Signal Processing, 2002 Traditionally, data hiding and compression have had contradictory goals. The former problem adds perceptually irrelevant information in order to embed data, while the latter removes this irrelevancy and redundancy to reduce storage requirements. In this
