de Vries, Chiel (author)Alzheimer's disease (AD) is becoming more prevalent as the world population gets older. The formation of Amyloid-beta (\AB) plaques is one of the pathologies related to AD. Recent work has shown that the \ab load in brain tissue has a negative correlation with cognitive performance in cognitively healthy centenarians. <br/>This work aims to...master thesis 2023

Ji, Ning (author)Emulsions, characterized as a metastable dispersion of one liquid into a second one in the presence of surface-active agents, have complex rheology that interests both physicists and industries. Depending on the volume fraction of the dispersed phase ($\phi$), emulsions can display both solid-like and liquid-like behavior. Rheometrical...master thesis 2023

Chen, Si-Jing (author)At crime scenes, various methods can be used to determine how much time has passed since the act happened, for example a body left at the scene, camera footage or eye witnesses. In this thesis, however, a different method shall be used to determine the time of the crime. The time will be determined using blood evidence. <br/><br/>To be exact,...bachelor thesis 2023

Stellinga, Bram (author)The segmentation of anatomical structures in 3D medical images is crucial for various applications in the field of medical imaging. Fully automated methods often lack accuracy, while manual segmenting requires much time and effort from a user. Due to this, Active Learning approaches are being proposed to solve this by making the method...bachelor thesis 2023

de Vries, J.J. (author), Laan, Daphne M. (author), Frey, F.F.F. (author), Koenderink, G.H. (author), de Maat, Moniek P.M. (author)Fibrous networks are essential structural components of biological and engineered materials. Accordingly, many approaches have been developed to quantify their structural properties, which define their material properties. However, a comprehensive overview and comparison of methods is lacking. Therefore, we systematically searched for...journal article 2023

Owen, C.C. (author), Hendrikse, H. (author)The manual application of universal (Rigsby) stage techniques is commonly used to determine the fabric of thin sections of ice viewed with crossed-polarized light. This process can require hours of focus in cold conditions to identify the c-axis of each grain in a thin section. Automated ice texture and fabric methods of several forms exist...journal article 2023

(author), Bertolini, Alessandro (author), van Heijningen, Joris (author), Bouwens, Bram (author), de Gaay Fortman, Nelson (author), van der Reep, Tom (author), Otemann, Lennart (author)The Rasnik system is a 3-point optical displacement monitor with sub-nanometer precision. The CCD-Rasnik alignment system was developed in 1993 for monitoring the alignment of the muon chambers of the ATLAS Muon Spectrometer at CERN. Since then, the development has continued as new CMOS imaging pixel chips became available. In this work the...journal article 2023

Shi, Rui (author), Wüthrich, D. (author), Chanson, Hubert (author)Continuing from the part 1 (Shi et al., 2022) this paper presents an experimental investigation of transient void fraction and bubble statistics in a highly turbulent breaking bore with Fr<sub>1</sub>=2.4. The measurements were conducted using a combination of dual-tip phase-detection probes and an ultra-high-speed video camera. The enclosed...journal article 2023

Ilioudi, A. (author), Wolf, B.J. (author), Dabiri, A. (author), De Schutter, B.H.K. (author)The majority of computer vision architectures are developed based on the assumption of the availability of good quality data. However, this is a particularly hard requirement to achieve in underwater conditions. To address this limitation, plenty of underwater image enhancement methods have received considerable attention during the last...conference paper 2023

Li, X. (author)Fatigue damage of composite laminates has attracted considerable attention from research community and industry, in view that laminated structures are inevitable to suffer from fatigue loading during their service life. It is rather complicated to understand and explain, what governs the initiation, accumulation, interaction (synergy or...doctoral thesis 2022

Wong, Jing Jing (author)This research consists of two applications of image processing, namely, image compression and image denoising. Image compression aims to reduce the size of an image without losing too many features. This is often used to store a large number of images such as fingerprints. Denoising is a technique for removing noise from an image while...bachelor thesis 2022

van der Toorn, Jules (author)Multimodal imaging is used by conservators and scientists to study the composition of paintings. To aid the combined analysis of these scans, such images must first be aligned. Rather than proposing a new domain-specific descriptor, we explore and evaluate how existing feature descriptors from related fields can improve the performance of...bachelor thesis 2022

Ordeman, Sam (author)Digital Soil Mapping (DSM) of soil types in geotechnical project areas is a top priority. These maps are often used in decision making and can have significant consequences related to costs and risks. Usually, these maps are generated by digital soil models that interpolate soil types at known locations. In practice, conventional spatial...master thesis 2022

van Noppen, Thirza (author)Second-order Gaussian kernels have been utilized to develop three algorithms that could automatically extract ridge lines for hydrodynamic modelling. Isotropic second-order Gaussian kernels produce inaccurate lines at crossings and junctions. To avoid the malfunctioning of Second-order Gaussian kernels, one default and two alternative algorithms...master thesis 2022

Coudert-Osmont, Yoann (author), Eisemann, E. (author), Marroquim, Ricardo (author)Perspective cues play an important role in painting analysis as it may unveil important characteristics about the painter's techniques and creation process. Nevertheless, extracting perspective lines and their corresponding vanishing points is usually a laborious manual task. Moreover, small variations in the lines may lead to large variations...conference paper 2022
