Mixture gradient detector for subpixel detection

Abstract

Subpixel detection is an important but difficult problem in hyperspectral image. Due to the small size of the target, only spectral information can be used for detection. Many algorithms have been proposed to reduce this problem, and most of them assume that the distribution of hyperspectral image is multinormal. However, this assumption may not be an… (More)
