Advanced Method for Small-Size Targets Detection in Hyperspectral Image

Vitaly V. Andronov

Abstract


The advanced method for subpixel detection of small-size targets on hyperspectral image is described. The method is based on matched filtering model with the succeeding correction of determined pixel fractions. Correction consists of two stages. First one is a statistical adjustment for actual set of targets/backgrounds in a scene and second one is a pixel-wise consideration of radiometric separability of spectra. The proposed advanced method provides more exact subpixel detection of small-size targets in hyperspectral image.


Keywords


Hyperspectral imagery, matched filtering, subpixel target detection, pixel fraction.
