Application of IDL and ENVI redevelopment in hyperspectral image preprocessing

Abstract

In the last few years, hyperspectral imaging technique has had a bright future for application on nondestructive detection of agricultural products. However, in experiment, there are usually dozens or even hundreds of hyperspectral images. It needs to spend lots of time in preprocessing all the hyperspectral data. Software ENVI is a kind of image processing software, although the users can define their own algorithms and apply to the opened bands in ENVI or the bands and spectra operation of the images, it doesn't provide program to batch process. In this paper, the custom function "normalized" of Interactive Data Language (IDL) is applied to achieve batch processing on multiple hyperspectral images. © 2011 IFIP International Federation for Information Processing.
