We consider the use of perceptual image quality assessment for quantization table (QT) optimization for JPEG compression. For evaluating performance, we consider the use of the Structural Similarity ...

Digital images are the most common cover files used for steganography. In this paper, a new steganography method called JMQT based on modified quantization table is proposed. This steganography method ...

Betalains are tyrosine-derived pigments that consist of red-violet betacyanins and yellow betaxanthins. These pigments are major sources of natural food dyes in the United States. Decades of table ...

Rivers and streams are a significant source of carbon, releasing both carbon dioxide and methane from their surface waters into the atmosphere. The vast ...
