Silhouette extraction involves separating objects of interest from their background, which has several applications in image processing. Among the silhouette extraction techniques, contour tracing is commonly applied to images with a uniform background. This paper introduces a novel contribution to&#x...

One of the main performance-heavy areas in raytracing is light sampling. Light sampling is solved in a process called next-event estimation(NEE), where light samples are taken at each ray intersection. Since real-time rendering is an objective, instead of sampling all the luminaries, ju...

The article focuses on a method for reliably identify moving colored artificial markers in real-time. The marker was used to determine the 3D position in the space of the user(s). The goal was to ensure that points were found and identified predictably and reliably by&#x...

The paper discusses the analysis of natural lighting conditions for digitizing art. The emphasis is on a realistic 3D digital reproduction of a work of art in natural lighting conditions in the interior of an art gallery. The art object is scanned and digitized in&...
