Lossless and nearly lossless digital video coding (2002)
Abstract / truncated to 115 words
In lossless coding, compresssion and decompression of source data result in the exact recovery of the individual elements of the original source data. Lossless image / video coding is necessary in applications where no loss of pixel values is tolerable. Examples are medical imaging, remote sensing, in image/video archives and studio applications where tandem- and trans-coding are used in editing, which can lead to accumulating errors. Nearly-lossless coding is used in applications where a small error, defined as a maximum error or as a root mean square (rms) error, is tolerable. In lossless embedded coding, a losslessly coded bit stream can be decoded at any bit rate lower than the lossless bit rate. In this ...
embedded to lossless coding – near-lossless coding – integer-to-integer transforms – integer-to-integer dct – in-transform quantization – spatially adaptive lifting – adaptive quadtree splitting.
