Latent Variable Model for Multi-modal Translation [PDF]

open access: yes, 2019
In this work, we propose to model the interaction between visual and textual features for multi-modal neural machine translation (MMT) through a latent variable model. This latent variable can be seen as a multi-modal stochastic embedding of an image and

Variational inference for medical image segmentation [PDF]

open access: yes, 2016
Variational inference techniques are powerful methods for learning probabilistic models and provide significant advantages over maximum likelihood (ML) or maximum a posteriori (MAP) approaches.

A new image deconvolution method with fractional regularisation

open access: yesJournal of Algorithms & Computational Technology, 2016
Image deconvolution is an important pre-processing step in image analysis which may be combined with denoising, also an important image restoration technique, and prepares the image to facilitate diagnosis in the case of medical images and further ...

Application of Variational AutoEncoder (VAE) Model and Image Processing Approaches in Game Design

open access: yesSensors, 2023
In recent decades, the Variational AutoEncoder (VAE) model has shown good potential and capability in image generation and dimensionality reduction. The combination of VAE and various machine learning frameworks has also worked effectively in different ...

Functional Liftings of Vectorial Variational Problems with Laplacian Regularization

open access: yes, 2019
We propose a functional lifting-based convex relaxation of variational problems with Laplacian-based second-order regularization. The approach rests on ideas from the calibration method as well as from sublabel-accurate continuous multilabeling ...

Power mean based image segmentation in the presence of noise

open access: yesScientific Reports, 2022
In image segmentation and in general in image processing, noise and outliers distort contained information posing in this way a great challenge for accurate image segmentation results.

On convergent finite difference schemes for variational–PDE-based image processing [PDF]

open access: yesComputational and Applied Mathematics, 2017
We study an adaptive anisotropic Huber functional based image restoration scheme. By using a combination of L2-L1 regularization functions, an adaptive Huber functional based energy minimization model provides denoising with edge preservation in noisy digital images.

Global Variational Method for Fingerprint Segmentation by Three-part Decomposition

open access: yes, 2015
Verifying an identity claim by fingerprint recognition is a commonplace experience for millions of people in their daily life, e.g. for unlocking a tablet computer or smartphone.

Decomposition of Optical Flow on the Sphere [PDF]

open access: yes, 2014
We propose a number of variational regularisation methods for the estimation and decomposition of motion fields on the $2$-sphere. While motion estimation is based on the optical flow equation, the presented decomposition models are motivated by recent ...

Image Processing Variations with Analytic Kernels

open access: yes, 2012
Let $f\in L^1(\R^d)$ be real. The Rudin-Osher-Fatemi model is to minimize $\|u\|_{\dot{BV}}+ \|f-u\|_{L^2}^2$, in which one thinks of $f$ as a given image, $ > 0$ as a "tuning parameter", $u$ as an optimal "cartoon" approximation to $f$, and $f-u$ as "noise" or "texture". Here we study variations of the R-O-F model having the form $\inf_u\{\|u\|_{\
