Design of Fast Algorithms for Pixel Purity Index for Endmember Extraction in Hyperspectral Imagery

Abstract

This paper presents new fast algorithms to improve the widely used endmember extraction algorithm, called pixel purity index (PPI) and also modify a revised version of PPI, called block of skewers (BOS) method. Since both the PPI and the BOS method suffer from same drawbacks in implementation, our proposed algorithms are designed to mitigate these dilemmas… (More)
