THMGUI: A user-friendly Matlab graphical user interface of Tchebichef-Hermite moment method for handing three-dimensional landscapes

Abstract This paper describes the development and implementation of THMGUI, a graphical user interface (GUI) for implementing the Tchebichef-Hermite moment (THM) method for quantitative analysis purpose on the basis of three-dimensional (3D) landscapes. It consists of four modules, namely “Import data”, “Image moment method”, “Splitting” and “Regression”. The THMGUI allows a user to apply the implemented methods in an easy way, in which the characteristic features acquisition, model establishment and its subsequent application in the analysis of unknown samples are straightforward from the interface. Moreover, the established models that involve the statistical parameters, and prediction results are conveniently managed through THMGUI shells and can be presented intuitively. For illustrating, an example involving the quantitative determination of two components on the basis of LC-MS 3D landscapes is presented.
