Segmentation tool for images of cracks

1 code implementation28 Mar 2024 Andrii Kompanets, Remco Duits, Davide Leonetti, Nicky van den Berg, H. H., Snijder

Machine learning algorithms can be used for augmenting the capability of classical visual inspection of bridge structures, however, the implementation of such an algorithm requires a massive annotated training dataset, which is time-consuming to produce.

PDE-CNNs: Axiomatic Derivations and Applications

no code implementations22 Mar 2024 Gijs Bellaard, Sei Sakata, Bart M. N. Smets, Remco Duits

PDE-based Group Convolutional Neural Networks (PDE-G-CNNs) utilize solvers of geometrically meaningful evolution PDEs as substitutes for the conventional components in G-CNNs.

Optimal Transport on the Lie Group of Roto-translations

no code implementations23 Feb 2024 Daan Bon, Gautam Pai, Gijs Bellaard, Olga Mula, Remco Duits

We develop a Sinkhorn like algorithm that can be efficiently implemented using fast and accurate distance approximations of the Lie group and GPU-friendly group convolutions.

Analysis of (sub-)Riemannian PDE-G-CNNs

no code implementations3 Oct 2022 Gijs Bellaard, Daan L. J. Bon, Gautam Pai, Bart M. N. Smets, Remco Duits

Typically, G-CNNs have the advantage over CNNs that they do not waste network capacity on training symmetries that should have been hard-coded in the network.

Roto-Translation Equivariant Convolutional Networks: Application to Histopathology Image Analysis

1 code implementation20 Feb 2020 Maxime W. Lafarge, Erik J. Bekkers, Josien P. W. Pluim, Remco Duits, Mitko Veta

This study is focused on histopathology image analysis applications for which it is desirable that the arbitrary global orientation information of the imaged tissues is not captured by the machine learning models.

PDE-based Group Equivariant Convolutional Neural Networks

1 code implementation24 Jan 2020 Bart Smets, Jim Portegies, Erik Bekkers, Remco Duits

We solve the PDE of interest by a combination of linear group convolutions and non-linear morphological group convolutions with analytic kernel approximations that we underpin with formal theorems.

Lesion Segmentation in Ultrasound Using Semi-pixel-wise Cycle Generative Adversarial Nets

no code implementations6 May 2019 Jie Xing, Zheren Li, Biyuan Wang, Yuji Qi, Bingbin Yu, Farhad G. Zanjani, Aiwen Zheng, Remco Duits, Tao Tan

The method takes the advantage of a fully convolutional neural network (FCN) and a generative adversarial net to segment a lesion by using prior knowledge.

Retrieving challenging vessel connections in retinal images by line co-occurrence statistics

no code implementations20 Oct 2016 Samaneh Abbasi-Sureshjani, Jiong Zhang, Remco Duits, Bart ter Haar Romeny

We propose to find line co-occurrence statistics from the centerlines of blood vessels in retinal images and show its remarkable similarity to a well-known probabilistic model for the connectivity pattern in the primary visual cortex.

Template Matching via Densities on the Roto-Translation Group

no code implementations10 Mar 2016 Erik J. Bekkers, Marco Loog, Bart M. ter Haar Romeny, Remco Duits

We propose a template matching method for the detection of 2D image objects that are characterized by orientation patterns.

Invertible Orientation Scores of 3D Images

no code implementations28 May 2015 Michiel Janssen, Remco Duits, Marcel Breeuwer

The enhancement and detection of elongated structures in noisy image data is relevant for many biomedical applications.

Numerical Approaches for Linear Left-invariant Diffusions on SE(2), their Comparison to Exact Solutions, and their Applications in Retinal Imaging

no code implementations13 Mar 2014 Jiong Zhang, Remco Duits, Gonzalo Sanguinetti, Bart M. ter Haar Romeny

We also provide an improvement of Mathematica algorithms for evaluating Mathieu-functions, crucial in implementations of the exact solutions.

Vesselness via Multiple Scale Orientation Scores

no code implementations20 Feb 2014 Julius Hannink, Remco Duits, Erik Bekkers

The multi-scale Frangi vesselness filter is an established tool in (retinal) vascular imaging.

A Multi-Orientation Analysis Approach to Retinal Vessel Tracking

no code implementations14 Dec 2012 Erik Bekkers, Remco Duits, Tos Berendschot, Bart ter Haar Romeny

This paper presents a method for retinal vasculature extraction based on biologically inspired multi-orientation analysis.
