App Description
Colorimetric analysis in mobile devices using USB Video Camera
Using USB Video Camera this app employs Single Linear Correlation technics for univariate analysis, Principal Component Analysis (PCA) and HCA for multivariate exploratory analysis and Partial Least Squares (PLS) form multivariate analysis. The image data are acquired using the device main camera and converted in RGB histograms. In addition, apart color channels of RGB, HSV, HSL and HSI systems are used during the univariate and multivariate processes. It is possible to send by e-mail the image data, analysis data and charts. In order to validate the obtained results, the same sets of data were tested using Microsoft Excel© and ChemoStat©. The results in both applications coincided in various combinations.
This app calculates: eigenvalues, eigenvectors, scores, loadings, latent variable, RMSEP, REMSEC using Singular Value Decomposition in Multivariate Analysis.
Also calculates: slope (span), intercept (off-set) and regression (Pearson product-moment correlation coefficient) in Univariate Calibration Analysis.
Also available in iOS and Windows Phone.
