A GUI for MIA of multispectral image data sets (PCA, Simplisma, MCR, classification) and basic processing techniques (threshold, histogram, profile plotting, image filters filters)
Runs under both MATLAB 14 and 13 versions.
Please e-mail me directly if problems/errors are found.
I really appreciate your feedback!
Requires Image Processing Toolbox.
Requires PLS_Toolbox.
Contains following Multivariate routines:
- PCA, Simplisma (pure variable method) and MCR (Multivariate Curve Resolution);
- Three types of image classification (2 unsupervised (K means, Fuzzy C) and 1 supervised (Maximum Likelihood)).
Basic image processing (from IP toolbox):
- cropping, resizing
- Filtering:
- averaging
- contrast enhancement
- morphological (opening, closing, eroding, dilation)
- edge extraction
- histogram equalization (GUI histogram.m)
- threshold (GUI threshold.m)
- profile plotter(GUI profile.m)
Works with most types of image formats:
- JPEG, TIFF, BMP and more (see imread.m for format types)
- RGB images are converted to grayscale
- mat files containing three-dimensional arrays: [m x n x p]
- Works with TEXT files containing image arrays or individual files
- Works with Kratos VAMAS format XPS photoelectron images *.vms
To run, type:
image_mva
Following GUIs can be used individually. Look in help for the instructions.
