Interval methods in computer graphics

WebA new method for ray tracing parametric surfaces is developed. The method uses a divide-and-conquer strategy for rapid finding of the sectors of constant intensity. Techniques from interval analysis allow reducing the number of ray/surface intersections that must be computed. Main results are presented in terms of solving a general system of nonlinear … WebThe DDA algorithm is a faster method for calculating pixel positions than the direct use of Eq. 2.1(refer Lecture 7 notes). It eliminates the multiplication in Eq. 2.1 by making use of …

Structure-Texture Decomposition of Images with Interval …

WebAbstract. This paper presents a novel filtering-based method for decomposing an image into structures and textures. Unlike previous filtering algorithms, our method adaptively smooths image gradients to filter out textures from images. A new gradient operator, the interval gradient, is proposed for adaptive gradient smoothing.
