Evaluation of JP3D for Lossy and Lossless Compression of Hyperspectral Imagery
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 KarhunenLo`eve 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 experimental 3D contexts. Results reveal that, while for lossless coding, JP3D very slightly surpasses the performance of JPEG2000 Part 2, for lossy coding, JP3D fails to match the rate-distortion performance of the 2D Part-2 coder.
