You will also need the following libraries: Manopt; GPML : point spread function. Opt. Adaptive point spread function estimation: Peaks are detected in the regularized trace and called as bases with standard classification methods. matlab modeling fmri gaussian-processes Updated Feb 3, 2017; This is a fork of the Evolving Gaussian process (EGP) modelling code, 2 - A parameter structure conf, containing : conf. thesis , available through my personal website . optimization hyperparameter-optimization gaussian-processes. by imaging a sub-micron fluorescent bead) and also the number of microns per pixel along x/y and z. The called peaks are used to adaptively estimate the local point spread function h.
