Integrating Shape-from-Shading & Stereopsis
… by combining two specific techniques: shape-from-shading and stereopsis. Shape-from-shading calculates shape using the lighting equation, which takes surface orientation and lighting information to irradiance. As irradiance and lighting information are provided this is the problem of inverting a …

Shading coils for alternating current electromagnets
In general, contrary to popular opinion. heavy shading coils are not as effective in reducing noise in an alternating current electromagnet as those which are smaller and thus have a greater value of resistance. This occurs because in addition to obtaining the greatest shift possible between flux …

Computational methods for the shape from shading problem
… explore computational methods for the shape from shading problem as formulated through the image irradiance equation. We seek to develop robust, efficient methods and test our algorithms on synthetic images ranging from simple smooth surfaces to complex digital terrain model data. We consider …

Modelling the human perception of shape-from-shading
Shading conveys information on 3-D shape and the process of recovering this information is called shape-from-shading (SFS). This thesis divides the process of human SFS into two functional sub-units (luminance disambiguation and shape computation) and studies them individually. Based on results of …

Computer Generation of Integral Images using Interpolative Shading Techniques
… depth cues include overlapping or occlusion, shading and shadows, texture etc. Another monocular cue is accommodation (and binocular to some extent) where the focal length of the crystalline lens is adjusted to view an image. The important binocular cues are convergence and parallax. …

Combining Probabilistic Shape-from-Shading & Statistical Facial Shape Models
… approach to combine a probabilistic Shape-from-Shading algorithm with statistical models of facial shapes. Thesis presents how Fisher-Bingham (FB8) distributions are sampled using Gibbs sampling to give normal distributions on the tangent plane. These normal distributions are in turn combined …

Design and manufacturing analysis of a window shading system
In this thesis a novel concept for a window shading system was proposed and developed. This concept was created to address issues with an existing Lutron Electronics product. Over the past year and a half, concepts have been generated, tested and refined to produce a fully functional working …

The texture shading cache : an approach to asynchronous interactive illumination
… visualisation applications towards pixel shading. Rendering is increasingly becoming bound by illumination processes and as a result, many interactive applications tend to make use of techniques that try to mimic the effects of light transport algorithms, sacrificing correctness while …

Effects of Pier Shading on Salt Marsh Plants in Mississippi
… on one potential threat, the effect that pier shading has on prominent saltmarsh plants of Mississippi, <em>Sporobolus alterniflorus</em> and <em>Juncus roemarianus</em>. Sample piers were selected in the three coastal counties of Mississippi and visited at two time periods (2006 and 2021). I …

Estimation of shape, lighting, and reflectivity from stereo and shading information
… is concerned with the combined use of stereo and shading information for the purpose of three-dimensional surface shape estimation. The applicability, resolution, and accuracy of each individual method is examined and compared with that attainable in a combined approach. Integration is examined …

Decision-Making Framework for the Selection and Design of Shading Devices
Most shading device systems installed in windows or glass walls are used only for protection from overheating and glare, neglecting other possible functions, such as increasing the daylight level in the space or collecting solar energy. The blinds are usually made of opaque or translucent …
