Quantitative performance measures of color transformations in hybrid vector scalar quantization
… applications, as well as image compression via JPEG, JPEG 2000, and Hybrid Vector Scalar Quantization Compression (HVSQ) methods. The objective is to utilize color spaces to optimize HVSQ compression, thereby enabling it to supersede such compression standards as JPEG and JPEG 2000. So in order …

Hyperspectral Image Compression Using a Two-Stage KLT
… such a limitation by leveraging the standard JPEG 2000 technology. The component decorrelation of the JPEG 2000 (extension 2) is replaced with a two-stage Karhunen-Loeve Transformation (KLT) operation resulting in a reduction in the computational complexity. At the first stage the spectral …

Image Quality Evaluation in Lossy Compressed Images
… was implemented to assess perceived quality of JPEG 2000 against baseline JPEG over a range of different scene types. Interval scales were generated for both algorithms, which indicated a subjective preference for JPEG 2000, particularly at low bit rates, and these were confirmed by an objective …

Jádra schématu lifting pro vlnkovou transformaci
… nakonec začleněn do kompresního řetězce formátu JPEG 2000, ve kterém se ukázal být zásadně rychlejší než široce používané implementace.

ROBUST WATERMARKING TECHNIQUES FOR SCALABLE CODED IMAGE AND VIDEO
… various content adaptation attacks, such as, JPEG 2000 for image and Motion JPEG 2000, MC-EZBC and H.264/SVC for video, are reported. The spread spectrum domain, particularly wavelet-based image watermarking schemes often provides better robustness to compression attacks due to its …

A Study of Perceptually Tuned, Wavelet Based, Rate Scalable, Image and Video Compression
… international still image compression standard - JPEG 2000. On the other hand, our codec also shows significant better speed performance and comparable visual quality in comparison to the best codec available in rate scalable color image compression - CSPIHT that is based on Set Partition In …

Application of Wavelets to Filtering and Analysis of Self-Similar Signals
… is data compression, such as described in the JPEG 2000 standard and compressed digital storage of fingerprints developed by the FBI. Previous work on filtering has focused on the discrete wavelet transform. Here, we extended that method to the stationary wavelet transform and found that it …

An intelligent system for the classification and selection of novel and efficient lossless image compression algorithms
… the average storage saving of the BBWCA, JPEG 2000 LS, KMTF– BWCA, HEVC and basic BWCA algorithms by 2.5%, 15.6%, 41.6%, 7.8% and 45.07% respectively. The CSC algorithm simple implementation positively affects the execution time and makes it one of the fastest algorithms, since it needed …
