[3] [4] [5] Kakadu library is heavily optimized and is a fully compliant implementation. Also, it has built-in multi-threading. [2] In a 2007 study Kakadu outperformed the JasPer library in terms of speed. [6] A more thorough comparison done in 2005, however, has shown that Kakadu does not achieve the best performance, in terms of compression ...

The main steps of lossless operation mode are depicted in Fig.2. In the process, the predictor combines up to three neighboring samples at A, B, and C shown in Fig.3 in order to produce a prediction of the sample value at the position labeled by X. The three neighboring samples must be already encoded samples.
