The performance of the recent JPEG2000 Part 10 standard, known as JP3D, is evaluated for the lossy and lossless compression of hyperspectral imagery. Experimental results using a Karhunen-Loève transform (KLT) for spectral decorrelation and a 2D wavelet transform for spatial decorrelation compare the performance of JP3D against 2D JPEG2000 as specified by Part 2 of the standard. JP3D is used with both the 2D arithmetic-coding contexts as specified in the JP3D standard as well as non-standard
