Hoveling, Vera (author)This document describes the work performed the master thesis on a new approach to visualisation for music. We investigate how visualisation of (latent) characteristics of a song can improve user-guided search and exploration. The need for such visualisation is described, followed by a formulation of the research questions, literature reviews,...master thesis 2023

Scholtens, Ekko (author)In this paper, we present a study to improve using neural networks for acoustic reflection localization. Our study focuses on the reimplementation of the proposed neural network model by Bologni et al. and investigates the effect of adding a third microphone to the microphone array. We reimplemented and trained the neural network using the same...bachelor thesis 2023

Flipse, Delano (author)The placement of a subwoofer has significant impact on the quality of its sound reproduction. This paper present a method to optimise subwoofer placement in a room. Resonances caused by room boundaries (called "room modes") cause localised peaks and lows for specific lower frequencies. The goal is to minimize the simulated frequency response...bachelor thesis 2023

Azimullah, Joshua (author)A novel approach for determining the optimal location of a sound source within an acoustic environment is proposed. This approach involves the application of Importance Sampling to improve the efficiency of the existing method of acoustic ray-tracing for finding the frequency response at various listening locations. The results of this study do...bachelor thesis 2023

Korpel, Dennis (author)The human visual system perceives 3D depth by observing how much points shift between the left eye and right eye. Toon-shaded renders of 3D models often have untextured surfaces with discretized shading, and these flat featureless areas give the eyes few reference points to perceive 3D depth. The primary depth cues come from contour lines and...master thesis 2022

van Geffen, Hunter (author)t-distributed stochastic neighbor embedding (t-SNE) is a dimensionality reduction technique able to embed high-dimensional data into 2 or 3 dimensions for the purpose of visualization, and has proven to be useful in various applications, such as single-cell analysis. Normally t-SNE embeds into Euclidean space, but recent work shows that...master thesis 2022

Zaidi, Amir (author)In the field of computer vision, the difficulty of processing the illumination in an arbitrary scene creates complications for a machine's understanding of the scene. Computer vision algorithms commonly use input images acquired by a camera, where the only measured quantity is the amount of light the camera's sensor receives without any...master thesis 2022

van Dijk, Robert (author)The appearance of an object or scene is determined by factors like the material, the lights, the geometry, the position of the observer, and the surroundings.<br/>Changes in these factors can be simulated using a projector-camera setup.<br/>Other research focuses on changing the appearance from the perspective of the projector, or on projector...bachelor thesis 2022

Cording, Henry (author)Diminished reality (DR) is an extension of augmented reality (AR) in which real objects are concealed, removed, or replaced. State of the art DR implementations are written and evaluated on desktop platforms, and those which are aimed at smartphones use auxiliary data or hardware for image completion. This paper introduces a DR app for Android...bachelor thesis 2022

Maat, Alex (author)Augmented Reality (AR) tracking for mobile devices is not realiable in environments where large virtual content, such as an entire virtual building, is to be displayed to the user. This paper presents a study on how multiple on-site markers can be used to better align the virtual scene to the real-world environment to improve large-scale AR...bachelor thesis 2022

Rensen, Max (author)In this paper, a method is proposed for stylizing stereoscopic augmented reality, while attempting to retain temporal and visual coherence. By tracking an AR marker and estimating a disparity map from stereo images, world positions of anchor points are tracked across frames and images, in order to move them with the scene. Additionally, the...bachelor thesis 2022

Ayala Le Brun, Francisco (author)According to the Contrast Sensitivity Function, the contrast of different spatial frequency elements of an image will be seen differently depending on distance. We propose a method for compensating for these differences by acting on an image's frequency representation and manipulating the magnitudes of the individual wave functions composing the...bachelor thesis 2022

Becheanu, Luca (author)This paper introduces the concept of the Voronoi Split-Screen in Augmented Reality inside a Sailing Regatta visualization application. We are making use of existing methods in 2D environments and modifying them to treat the implications of merging the screen where a user has complete camera control (3D/AR/VR). This is done in three phases which...bachelor thesis 2022

Stroia, Marco (author)Chromostereopsis is an optical illusion that allows 2D images to simulate depth based on color. For example, red is perceived to be closer than blue, when displayed on a black background. This effect is present because of the slight chromatic aberration caused by the eye lens, and it can be strengthened by the use of ChromaDepth® glasses. This...bachelor thesis 2022

Jonker, Luc (author)For mobile augmented or virtual reality applications with limited processing power, representing realistic water geometry is a challenge. Many existing solutions are simulations that can only run at interactive rates on desktop computers. This paper presents a lightweight approximative approach to water representation achieved through mesh LOD...bachelor thesis 2022

Sjerps, Thomas (author)Chromostereoscopic images encode depth as colour, with the red part of the visible spectrum encoding nearby depths and the blue part encoding far-away depths. However, when encoding a regular image with its depth, the generated colours may not match with the original colours in the image. Following a user study, a technique has been developed...bachelor thesis 2022

Sundarrajan, Mathanrajan (author)Path tracing is a well-known light transport algorithm used to render photo-realistic images. However, it is an expensive algorithm with an active area of research for improving its efficiency. In our work, we present a method to measure and visualize the regions of high computational cost for unidirectional path tracers. We have defined metrics...bachelor thesis 2022

Westermann, Helena (author)The following paper explores the use of chromostereopsis for the purpose of enhancing the perceived depth in photos. Contrary to previous work, this is achieved by using a continuous depth map as input and creating a natural-looking photo with enhanced depth even when viewed without any type of three dimension technology. This is the first...bachelor thesis 2022

Romeu Huidobro, Jorge (author)Direct lighting calculation is an essential part of photorealistic rendering. Standard importance sampling techniques converge slowly in scenes where a light source is only visible through small openings as visibility is not considered. This problem is often addressed by manually placing light portals, marking the openings to the light. However,...bachelor thesis 2022

Deshmukh, Piyush (author)Spectral Monte-Carlo methods are powerful physically-based techniques for simulating wavelength-dependent phenomena such as dispersion. However, compared to tristimulus rendering, they involve sampling the spectral domain, which adds substantial overhead, requiring significantly more samples for noise-free, realistic-looking renders. Thereby, we...bachelor thesis 2022
