Software for hyper-spectral data pre-processing

by

 

07 Mar 2013 (Updated )

The software offers a user-friendly tool (based on two GUIs) for pre-processing reflectance spectra

call_ch_removal(varargin)
% -- THIS SOFTWARE HAS BEEN CREATED FOR PRE-PROCESSING REFLECTANCE SPECTRA ACHIEVED BY MEANS OF ASD SPECTRORADIOMETER --
% The software can be adapted to other instruments changing the function
% for file reading and the values that are entered in the fields of GUIs  
% SOFTWARE USE:
% This function (call_ch_removal.m) call call_ch_removal.fig (GUI1) that allows to insert the preliminary 
% options before callback to ch_removal.fig (GUI2). First the GUI1 allows to choice the type of ASD files,
% then it is possible to insert the extremes as wavelength to remove sensor bad calibration and atmospheric
% band with noise. While the GUI2 allows to pre-process the reflectance spectra.   

function varargout = call_ch_removal(varargin)
% CALL_CH_REMOVAL M-file for call_ch_removal.fig
%      CALL_CH_REMOVAL, by itself, creates a new CALL_CH_REMOVAL or raises the existing
%      singleton*.
%
%      H = CALL_CH_REMOVAL returns the handle to a new CALL_CH_REMOVAL or the handle to
%      the existing singleton*.
%
%      CALL_CH_REMOVAL('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in CALL_CH_REMOVAL.M with the given input arguments.
%
%      CALL_CH_REMOVAL('Property','Value',...) creates a new CALL_CH_REMOVAL or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before call_ch_removal_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to call_ch_removal_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
