Abstract
Mineral target identification and hydrothermally altered zone’s discrimination has been considered by many investors during many years of study. Numerous mineral targets can’t be recognized at pixel level. The problem of unmixing and resolving spectra in subpixel level of mixels (mixed pixels) was expressed with the birth of imaging spectrometry. On the other hand prober’s experiments have shown the improved results in ensemble of classifiers. This study have proposed the mixture of some target detectors and classifiers at both pixel and subpixel levels, which have been tested on the hymap airborne hyperspectral sensor, in Iran East. Results have shown that the proposed method has better performance than individual detectors.
