Color Super-Resolution from a Single CCD
Limitation in the resolution of CCD image sensors has provided motivation to enhance the resolution of images. Super-resolution has been applied mainly to grayscale images, and producing a high-resolution color image from a single CCD sensor has not been discussed thoroughly. This work aims at producing a high-resolution color image directly from ”color mosaic” images obtained by a singleCCD wi...
متن کاملHigh Resolution CCD Polarization Imaging Sensor
We present a novel polarization imaging sensor by monolithically integrating aluminum nanowire optical filters with an array of CCD imaging elements. The CCD polarization image sensor is composed of 1000 by 1000 imaging elements with 7.4m pixel pitch. The image sensor has a dynamic range of 65dB and signal-to-noise ratio of 45dB. The CCD array is covered with an array of pixel-pitch matched na...
متن کاملNumerical Uniformization of Hyperelliptic Curves
We develop algorithms which allow us to uniformize numerically any given real hyperelliptic plane M{curve. Starting from an equation for such a curve, we get ((oating point approximations) for the generators of a discontinuous group of MM obius transformations uniformizing the given M{curve. Furthermore, we show how to compute an equation for a Rie-mann surface given by a such a group. For real...
متن کاملInvariant Curves for Numerical Methods
The problem of finding periodic orbits of dynamical systems numerically is considered. It is shown that if a convergent, strongly stable, multi-step method is employed then under some suitable conditions, there exist invariant curves. The result also shows that the rates of convergence toward the invariant curves are roughly the same for different methods and different step sizes. Introduction....
متن کاملNumerical proper reparametrization of parametric plane curves
Proper reparametrization is a basic simplifying process for rational parameterized curves. There are complete results proposed for the curves with exact coefficients but few papers discuss the situations with numerical coefficients which have many practical applications. In this paper, we deal with mathematical objects that are assumed to be given approximately. The approximate improper index i...
