Depending on whether the block is found to contain natural or synthetic image content, transform coding (DCT) or graphic coding is applied. Because the different encoding modes have different properties as regards picture quality, the bitstream format has to enable the encoder to very flexibly ...

The coding is used when the channel capacity is limited or unknown or the decoding speed is not so fast. Various scalable image compression schemes have been discussed here. The state-of-the-art techniques developed until 2014 reconstruct images based on the quantized or latent space ...

1260Accesses Abstract HD video content represents a tremendous quantity of information that all types of devices can not easily handle. Hence the scalability issues in its processing have become a focus of interest in HD video coding technologies. In this chapter, we focus on the natural scalabilit...
The low complexity scheme of JPEG-LS is based on the assumption that prediction residuals follow a two-sided geometric distribution and the fact that Golomb-codes are optimal for geometric distributions, thus the modeling and coding units are matching. UHT-JPEGLS-E is very easy to use and ...
This method has been introduced for two descriptions in the context of image coding [148], and subsequently extend to more general mappings to produce an arbitrary number of descriptions [131,146]. It is worth noticing that, whereas in SDC quantization is performed after the transformation, ...
