Abstract

This paper first introduces the character of JPEG2000 and JPEG, a digital stereo aerial image pair is compressed using the JPEG2000 and JPEG method. Comparing are provided from subjective quality, PSNR and accuracy of digital terrain models (DTM) automatically derived from digital stereo aerial image pair. Experiment analysis is provided in the end, and result indicates that the JPEG2000 method has better effect.
