A Characterization of the Domain of Beta-Divergence and Its Connection to Bregman Variational Model
In image and signal processing, the beta-divergence is well known as a similarity measure between two positive objects. However, it is unclear whether or not the distance-like structure of beta-divergence is preserved, if we extend the domain of the beta-

Sobolev spaces with non-Muckenhoupt weights, fractional elliptic operators, and applications [PDF]
We propose a new variational model in weighted Sobolev spaces with non-standard weights and applications to image processing. We show that these weights are, in general, not of Muckenhoupt type and therefore the classical analysis tools may not apply ...

An Efficient Method for Euler’s Elastica Based Image Deconvolution
Variational models involving Euler's elastica energy have a wide range of applications in digital image processing. Recently, fast methods, such as the proximal-augmented Lagrangian method (PALM), have been successfully used to solve nonlinear higher ...

Fast Image Processing with Fully-Convolutional Networks [PDF]
We present an approach to accelerating a wide variety of image processing operators. Our approach uses a fully-convolutional network that is trained on input-output pairs that demonstrate the operator’s action.

Joint Demosaicing and Denoising Based on a Variational Deep Image Prior Neural Network
A joint demosaicing and denoising task refers to the task of simultaneously reconstructing and denoising a color image from a patterned image obtained by a monochrome image sensor with a color filter array.

Feature Reconstruction from Incomplete Tomographic Data without Detour
In this paper, we consider the problem of feature reconstruction from incomplete X-ray CT data. Such incomplete data problems occur when the number of measured X-rays is restricted either due to limit radiation exposure or due to practical constraints ...

Unsupervised Transformer Balanced Hashing for Multispectral Remote Sensing Image Retrieval
For remote sensing (RS) image retrieval task, hashing technology have been extensively researched in recent works. Unsupervised hashing approaches have attracted much attention in the RS data processing field because label collection takes a lot of time.
