Draft: Radial distortion homography solvers

8

This PR is a draft containing the homography solvers discussed in #60. It is incomplete because of the following: * Naming convention. I gave a proposal in the README, but...

Homography solvers with radial distortion

2

Hi! Very nice library. I saw that you have added support for homographies. I have some implemented in Eigen here: https://github.com/marcusvaltonen/HomLib namely: Fitzgibbon (CVPR, 2001) Kukelova et al. (CVPR, 2015)...

Add support for proximal operator proposed in "Convex Low Rank Approximation" by Larsson and Olsson

5

In [1] a general low-rank inducing framework was introduced and showed many benefits compared to e.g. the nuclear norm when applied to common computer vision tasks. This was later generalized...

Add support for second-order low-rank inducing bilinear optimization frameworks (and related penalties)

3

There is already support for BilinearOperator in `pyproximal/pyproximal/utils/bilinear.py` and the PALM optimizer; however, they do not scale to second-order methods such as Levenberg-Marquardt (LM) and Variable Projection (VarPro). In recent...
