Image Zooming using Non-linear Partial Differential Equation
The main issue in any image zooming techniques is to preserve the structure of the zoomed image. The zoomed image may suffer from the discontinuities in the soft regions and edges; it may contain artifacts, such as image blurring and blocky, and staircase effects. This paper presents a novel image zooming technique using Partial Differential Equations (PDEs). It combines a non-linear Fourth-ord...
متن کاملHashing Image Patches for Zooming
In this paper we present a Bayesian image zooming/super-resolution algorithm based on a patch based representation. We work on a patch based model with overlap and employ a Locally Linear Embedding (LLE) based approach as our data fidelity term in the Bayesian inference. The image prior imposes continuity constraints across the overlapping patches. We apply an error back-projection technique, w...
متن کاملRotation and zooming in image mosaicing
Many methods are available for image mosaicing most of which are not useful because they either (1) require a great deal of overlap between images, or (2) if they work for restricted sub-problem (translation, rotation or zooming) they would not work for the others. While numerous methods exist for accurately calculating translational shifts, no method was found that could handle rotations of an...
متن کاملImage Point Motion When Zooming and Focusing
A method for modeling the image point motion as function of the degree of zoom and focus is described and evaluated. The method requires that the camera can be translated towards a frontoparallel grid of calibration marks. The evaluation shows that, for a translation span of 2 meters, a zoom range from 10 to 96 millimeter, and for focus settings between 1 meter and innnity, the average predicti...
متن کاملZooming In, Zooming Out
This is an exploratory paper about combining logics, combining theories and combining structures. Typically when one applies logic to such areas as computer science, artificial intelligence or linguistics, one encounters hybrid ontologies. The aim of this paper is to identify plausible strategies for coping with ontological richness.
