In the course of a seminar on “Selected Topics in Image Processing”, I worked on iPiano, an algorithm for non-convex and non-smooth optimization proposed by Ochs et al. [1]. iPiano combines forward-backward splitting with an inertial force. This article presents the corresponding seminar paper including an implementation in C++ with applications to image denoising, image segmentation and compressed sensing.
Efficient C++ implementation of iPiano, a proximal algorithm with inertial force for non-convex and non-smooth optimization; including applications to image segmentation.
Ochs et al. proposed iPiano, a proximal algorithm with inertial force for non-convex and non-smooth optimization. This article presents a C++ implementation which was written as part of a seminar on “Selected Topics in Image Processing”.
