Image Interpolation with Geometric Contour Stencils
We consider the image interpolation problem where, given an image v with uniformly-sampled pixels vm,n and point spread function h, the goal is to find a function u(x, y) satisfying vm,n = (h ∗ u)(m,n) for all m,n ∈ Z (1) so that u approximates the underlying function from which v was sampled. This article improves upon the IPOL article “Image Interpolation with Contour Stencils” [7]. In the pr...
متن کاملImage Interpolation with Contour Stencils
Image interpolation is the problem of increasing the resolution of an image. Linear methods must compromise between artifacts like jagged edges, blurring, and overshoot (halo) artifacts. More recent works consider nonlinear methods to improve interpolation of edges and textures. In this paper we apply contour stencils for estimating the image contours based on total variation along curves and t...
متن کاملImage Demosaicking with Contour Stencils
Demosaicking (or demosaicing) is the problem of interpolating full color information on an image where only one color component is known at each pixel. Most demosaicking methods involve some kind of estimation of the underlying image structure, for example, choosing adaptively between interpolating in the horizontal or vertical direction. This article discusses the implementation details of the...
متن کاملEdge Orientation Using Contour Stencils
Many image processing applications require estimating the orientation of the image edges. This estimation is often done with a finite difference approximation of the orthogonal gradient. As an alternative, we apply contour stencils, a method for detecting contours from total variation along curves, and show it more robustly estimates the edge orientations than several finite difference approxim...
متن کاملBRDF Interpolation using Anisotropic Stencils
Fast and reliable measurement of material appearance is crucial for many applications ranging from virtual prototyping to visual quality control. The most common appearance representation is BRDF capturing illuminationand viewing-dependent reflectance. One of the approaches to rapid BRDF measurement captures its subspace, using so called slices, by continuous movements of a light and camera in ...
