Lossless Compression of Hyperspectral Images Using Three-Stage Prediction with Adaptive Search Threshold
Changguo Li, Ke You Guo · International Journal of Signal Processing Image Processing and Pattern Recognition · 2014
We propose a new lossless compression algorithm for hyper spectral images based on the third-order interband predictor and the backward pixel search scheme (IP3-BPS). Specifically, we propose an adaptive search threshold algorithm and a bi-directional pixel search scheme. The resulting algorithm takes the bi-directional pixel search and the backward pixel search with adaptive search threshold as the last two predictors; its performance evaluation on Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) 1997 images shows that it outperforms the original IP3-BPS algorithm, at lower computational complexity level.
