Title: Shape-adaptive reversible integer lapped transform for lossy-to-lossless ROI coding of remote sensing two-dimensional images
Authors: Jiao, Licheng;Wang, Lei;Wu, Jiaji;Bai, Jing;Wang, Shuang;Hou, Biao
subject: Image compression;SA transform;region of interest (ROI);shape-adaptive (SA) discrete cosine transform (DCT) (SA-DCT);time domain lapped transform

Abstract: In this letter, we propose a shape-adaptive (SA) reversible integer lapped transform (SA-RLT) method. The new method can deal with arbitrarily shaped image areas while guaranteeing completely reversible integer-to-integer transform. Based on SA-RLT and object-based set partitioned embedded block coder, a new region-of-interest (ROI) compression scheme is designed for 2-D remote sensing images. Numerical experiments reveal that SA-RLT performs better than integer SA discrete wavelet transform, and the new ROI compression scheme performs comparably even better than the JPEG2000-ROI scheme. Advantages in hardware implementation have been preserved by SA-RLT, such as parallel processing and low memory requirement. © 2006 IEEE.
