In this chapter, data compression as it relates to multimedia information is studied from the point of view of lossless algorithms, where the input data is essentially exactly recoverable from the compressed data Lossy algorithms, for which this is not the case, are presented in Chapter 8. Here...

Based on LOCO-I (LOw COmplexity LOssless COmpression for Images), the JPEG-LS algorithm leads in numerically lossless compression efficiency, attaining compression ratios similar or superior to those obtained with more advanced algorithms such as JPEG2000. JPEG-LS also enables hardware implementations wi...
efficient: the code is optimized for efficiency (trade-off between compression ratio and speed). Unlike the most common lossless data compressors, Kanzi uses a variety of different compression algorithms and supports a wider range of compression ratios as a result. Most usual compressors do not tak...
It results in improving the compression ratios of all these images and for all compression algorithms in cases when unmodified color space transformation either improves or worsens ratios compared with the untransformed image. The average improvement is 5.0–6.0% for two out of the three sets of ...
And these algorithms are much smarter than they once were! But bit depth plays a big role in the final quality of the audio file. For example, severely reducing the bit depth – say to 16-bit down from 32-bit – then the fidelity of the audio will suffer. Here is a spectrogram ...
The role of compression is inevitable in the storage and transmission of medical images. The polynomial based image compression is proposed in this work for the compression of abdomen CT medical images. The input images are preprocessed by min–max normalization; the pixels are scanned and subjected...

introduce a two phase steganography application that allows the user to first compress the information into ASCII form using our novel compression technique (compression technique utilizing reference points coding) then embed the information into the carrier using least significant bit (LSB) algorithms. ...
