Burghouts, G.J. (author), Huizinga, W. (author)Visual Question Answering (VQA) is a very interesting tech nique to answer natural language questions about an image. Recent methods have focused on incorporating knowledge into an improved VQA model, by augmenting the training set, representing scene graphs, or including reasoning. We also leverage knowledge to make VQA more robust. Yet we take...conference paper 2022

Azzopardi, G. (author), Strisciuglio, N. (author), Vento, M. (author), Petkov, N. (author)Retinal imaging provides a non-invasive opportunity for the diagnosis of several medical pathologies. The automatic segmentation of the vessel tree is an important pre-processing step which facilitates subsequent automatic processes that contribute to such diagnosis. We introduce a novel method for the automatic segmentation of vessel trees in...article 2015

van Maanen, P.P. (author), Busschers, F.S. (author), Brouwer, A.M. (author), van der Meulen, M.J. (author), van Erp, J.B.F. (author)Due to an expected increase in geological voxel model data-flow and user demands, the development of improved quality control for such models is crucial. This study explores the potential of a new type of quality control that improves the detection of errors by just using gaze behavior of 12 geological experts. Gaze is used as input for an...article 2015

de Rooij, M.R. (author), Mendonca Filho, F.F. (author)In this article a trip is taken to characterize concrete through its hardened cement paste based on its microstructure. Optical microscopy is coupled to advanced image analysis, as well as statistical data analysis to characterize heterogeneous concrete material. The article takes a closer look at the determination of the w/c ratio through the...conference paper 2015

Pacheco, J. (author), Šavija, B. (author), Schlangen, E. (author), Polder, R.B. (author)The durability of cracked reinforced concrete is a serious concern in the construction industry. Cracks represent fast routes for chloride penetration, which can result in reinforcement corrosion. Bending or tapered cracks have the characteristic of being wider at the surface and becoming narrower towards the reinforcement. In reinforced...article 2014

Toet, A. (author)The predictions of 13 computational bottom-up saliency models and a newly introduced Multiscale Contrast Conspicuity (MCC) metric are compared with human visual conspicuity measurements. The agreement between human visual conspicuity estimates and model saliency predictions is quantified through their rank order correlation. The maximum of the...article 2011

Valcke, S. (author), Nijland, T.G. (author), Larbi, J.A. (author), TNO Bouw en Ondergrond (author), BenO (author)The water cement (w/c) ratio is a typical quality parameter for concrete. The NT Build 361 Nordtest method is a standard for estimating the w/c ratio in hardened concrete and is based on the relationship between the ilc ratio and the capillary porosity in the cement paste. The latter can be estimated using fluorescent light microscopy of...conference paper 2009

(author), TNO Bouw en Ondergrond (author)In three boys aged 15, 9, and 10 years respectively scrotal ultrasound revealed testicular microlithiasis (TM). Two boys were free of symptoms and one suffered from testicular pain. TM is characterized by multiple echogenic foci within the seminiferous tubules with no acoustic shadowing. The pathophysiology is largely unknown. In adult men, TM...article 2008
