Abstract - A pan-sharpening
method was proposed as the first step for building a global
monitoring system for temporal change of coral reef with
high accuracy and low cost. Firstly, low spatial resolution
multi-spectral image was enlarged (increasing number of
pixels) and co-registered onto panchromatic image. Based
on multiple regression analysis, brightness information
of the enlarged multi-spectral image was replaced with
that of the panchromatic image so that all spectral density
scatter-diagrams gave us linear shapes along the identical
line (unity gradients and zero y-intercept). The method
was characterized by its simplicity and faithfulness in
preserving color information.

“A method for detecting change in coral reef using
pan-sharpened satellite images,” in Proc. SPIE Asia

Abstract - A method
was developed for global monitoring of temporal change
of coral reef using pan-sharpened color images with higher
accuracy and lower cost. The method consisted of 3 blocks;
image co-registration for removing complex discrepancy
due to parallax among original color image and panchromatic
one, pan-sharpening with preserving color information,
and change detection with suppressing noise such as sea
waves. The method was successfully applied to an actual
FORMOSAT2 multi-temporal data set.
