The region of interest (ROI) coding feature of JPEG 2000 image compression standard is extended to multispectral imagery. This is accomplished by enabling ROI capability of JPEG 2000 module in the previously developed Karhunen-Loeve/JPEG 2000 compression of multispectral images. Preliminary results, based on subjective, statistical, and machine-based exploitation measures, show significant improvement in the compression performance. Depending on the ROI/background relative size and the desired quality differential, the improvement in the classification accuracy can increase by as much as one hundred percent without an increase in the bandwidth.
