Convolutional Dictionary Learning: A Comparative Review and New Algorithms
Cristina Garcia-Cardona, Brendt Wohlberg
Convolutional sparse representations are a form of sparse representation with a dictionary that has a structure that is equivalent to convolution with a set of linear filters. Whil…
First and Second Order Methods for Online Convolutional Dictionary Learning
Jialin Liu, Cristina Garcia-Cardona, Brendt Wohlberg +1
Convolutional sparse representations are a form of sparse representation with a structured, translation invariant dictionary. Most convolutional dictionary learning algorithms to d…
Convolutional Sparse Coding with Overlapping Group Norms
Brendt Wohlberg
The most widely used form of convolutional sparse coding uses an regularization term. While this approach has been successful in a variety of applications, a limitation of…
Convolutional Sparse Coding: Boundary Handling Revisited
Brendt Wohlberg, Paul Rodriguez
Two different approaches have recently been proposed for boundary handling in convolutional sparse representations, avoiding potential boundary artifacts arising from the circular…
Online Convolutional Dictionary Learning
Jialin Liu, Cristina Garcia-Cardona, Brendt Wohlberg +1
While a number of different algorithms have recently been proposed for convolutional dictionary learning, this remains an expensive problem. The single biggest impediment to learni…
Convolutional Sparse Representations with Gradient Penalties
Brendt Wohlberg
While convolutional sparse representations enjoy a number of useful properties, they have received limited attention for image reconstruction problems. The present paper compares t…
