چکیده
An integer reversible implementation of multiple component transform is significant for lossless, unified lossy/lossless and progressive lossy-lossless multi-component or hyper-spectral image coding. In this proposal, we present a reversible integer mapping method for invertible linear transforms. Its effectiveness was evaluated using 2 6-band Landsat TM images and an 80-component hyper-spectral image. The linear transforms we tested and compared are KLT, DWT, and a direct prediction transform. Both lossy and lossless compression performance were considered, as well as the computational complexity. Experiments with JPEG-2000 verification model (VM7.2) showed that KLT or reversible KLT outperforms other approaches for all of the images in the case of lossy and lossless compression.

JPEG 2000, the new ISO/ITU-T standard for still image coding, is about to be finished. Other new standards have been recently introduced, namely JPEG-LS and MPEG-4 VTC. This paper compares the set of features offered by JPEG 2000, and how well they are fulfilled, versus JPEG-LS and MPEG-4 VTC, as well as the older but widely used JPEG and more recent PNG. The study concentrates on the set of su...

In the middle of the third century BCE – some 2250 years ago – the Mauryan emperor Aśoka is thought to have directed the creation of the Brahmi script. Brahmi was used in all parts of India to write Prakrit and Sanskrit (except for the north-western regions where Kharoshthi was used to write Prakrit and Gandhari, and occasionally Sanskrit). Brahmi shows all the features found in the scripts des...
