We updated SaivDr (Sparsity-Aware Image and Volumetric Data Restoration) package for the first time in about six months.

New this time, we added custom layers and sample codes for use with MATLAB Deep Learning Toolbox. It allows for more flexible DAG configuration than before.

NSOLT enables you to realize Parseval tight, symmetric and multi-resolution convolutional layers, and you can place NSOLT as a convolutional layer in a corner of a convolutional neural network.

We hope you will give it a try.

Defined a prox plot MATLAB function.

Is it helpful?

function proxplot(f,varargin)
%PROXPLOT Plot prox of a scalar function
% Example
% >> proxplot(@(x) abs(x))
% See FPLOT
