A multiresolution technique for biomedical image interpolation is presented in this paper. It is an extension of the work on Directional Coherence Interpolation (DCI) [15] – a novel gray-level image interpolation method that interpolates the missing image data along the smoothed Maximum Coherence Directions (MCDs). We propose to apply a pyramidal search strategy for MCD estimation. This coarse-...

Single-chip digital cameras use a color filter array and subsequent interpolation strategy to produce full-color images. While the design of the interpolation algorithm can be grounded in traditional sampling theory, the fact that the sampled data is distributed among three different color planes adds a level of complexity. Existing interpolation methods are usually derived from general numeric...

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...
