# Multiband and Lossless Compression of Hyperspectral Images
## 4 Experimental Results
### 1997 AVIRIS Dataset  
Each one of AVIRIS hyperspectral image of the AVIRIS '97 dataset is subdivided into scenes (the number of scenes is highlighted in Table 1). It is important to note that each scene has 614 columns, 512 lines, and 224 spectral bands. In addition, each pixel is stored by using 16 bits. In Tables 2 and 3 we report the results achieved by using \(B=1\) with \(N=8\) and \(N=16\), respectively. Subsequently, in Tables 4 and 5 we report the results achieved, by using \(B=2\). Finally, Tables 6 and 7 report the results achieved by using \(B=3\) and the \(N\) parameter equal to 8 and equal to 16, respectively. All the results are reported in terms of _Bits Per Sample_ (_BPS_). In each table we report the results achieved by using both the AC and the PAQ8 schemes for the coding of the prediction errors. \begin{table}
