Global Minimization of Contrast Function with Multiple Random Restarts

Implementation of global minimization for contrast functions using random restart strategy, assuming whitened data (identity covariance matrix). The optimization yields Wopt*x as the independent sources through iterative comparison and selection.

The Widely Sought EM Algorithm

A MATLAB implementation of the EM algorithm that everyone is searching for, featuring complete probabilistic modeling and iterative optimization capabilities

Locating Image Center Points with Computational Methods

Images consist of multiple pixels that can be represented as single or multiple matrices. Automated center point detection in image processing eliminates tedious manual inspection processes and streamlines analysis workflows through algorithmic implementations.
