## 5 Experimental Results  
We have tested our Java-based implementation of the SLSQ algorithm on the test data set (a) without band ordering; (b) with [PERSON]'s correlation-based band ordering; and (c) [PERSON] distance-based band ordering. Our test data set is composed by five NASA AVIRIS hyperspectral images (each one subdivided into scenes): Lunar Lake (3 scenes), Moffett Field (4 scenes), Jasper Ridge (6 scenes), Cuprite (5 scenes) and Low Altitude (8 scenes). Each scene has 614 columns and 224 spectral bands. Table 1 reports the compression ratio (C.R.) achieved by SLSQ on the test data set. The columns indicate respectively the results achieved for Lunar Lake, Moffett Field, Jasper Ridge, Cupirte and Low Altitude. The IB set used is \(\text{IB}=\{1,\,2,\,\ldots,\,8\}\), with \(\text{M}=4\) and \(\text{N}=1\). Table 2 reports the results achieved in terms of C.R. by SLSQ (with the same settings) by using the proposed band ordering based on [PERSON]'s Correlation distance. As in Table 2, the columns indicate respectively the results for scene achieved for Lunar Lake, Moffett Field, Jasper Ridge, Cuprite and Low Altitude. \begin{table}

Table 1: Results (C.R. achieved for each scene of the hyperspectral imagery without band ordering). Table 3 reports the C.R. achieved by SLSQ by using the same parameters used above, this time for a band ordering based on Bhattacharyya distance. The following tables (Tables 4,5 and 6) report the achieved results in terms of Bit-Per-Pixel (BPP). Table 4 reports achieved results scene-by-scene for each hyperspectral image without band ordering, Table 5 similarly Table 2 reports achieved results in terms of BPP with proposed band ordering based on Pearson's correlation distance. Table 6 reports the achieved results in terms of BPP by SLSQ with Bhattacharyya distance-based band ordering. \begin{table}
