function varargout = image_mva_0_0(varargin)
% GUI for Multivariate Analysis of images
% Includes:
% PCA, Simplisma (pure variable method) and MCR (Multivariate Curve Resolution)
% Three types of image classification: 2 unsupervised and 1 supervised
% Basic image processing:
% - cropping, resizing
% - histogram equalization
% - threshold
% - profile plotter
% Filtering:
% - averaging
% - contrast enhancement
% - morphological (opening, closing, eroding, dilation)
% - edge extraction
%
% Works with most types of Image formats:
% JPEG, TIFF, BMP and more (see imread for format types)
% RGB images are converted to grayscale
% Can open MAT files containing variable IMAGES
% Works with TEXT files containing image arrays or individual files
% Works with Kratos VAMAS format XPS photoelectron images *.vms
%
% To run, type:
% image_mva_0
