Derivative-Free Superiorization: Principle and Algorithm
Yair Censor, Edgar Garduño, Elias S. Helou +1
The superiorization methodology is intended to work with input data of constrained minimization problems, that is, a target function and a set of constraints. However, it is based…
Texture Fuzzy Segmentation using Skew Divergence Adaptive Affinity Functions
José F. S. Neto, Waldson P. N. Leandro, Matheus A. Gadelha +3
Digital image segmentation is the process of assigning distinct labels to different objects in a digital image, and the fuzzy segmentation algorithm has been successfully used in t…
Computerized Tomography with Total Variation and with Shearlets
Edgar Garduño, Gabor T. Herman
To reduce the x-ray dose in computerized tomography (CT), many constrained optimization approaches have been proposed aiming at minimizing a regularizing function that measures lac…
Superiorization: An optimization heuristic for medical physics
G. T. Herman, E. Garduño, R. Davidi +1
Purpose: To describe and mathematically validate the superiorization methodology, which is a recently-developed heuristic approach to optimization, and to discuss its applicability…
