Fast Computation of the OTFs for Various Computational Cameras
نویسنده
چکیده
In this report, we discuss how to compute exactly and efficiently the optical transfer function (OTF) of various computational cameras, under the assumptions of far-field wave optics and ideal thin lens. Approximations of the magnitudes of the OTFs have been previously given in [8], with derivations for cubic phase plates given in [12]. For ease and simplicity of derivation, let us stipulate that the aperture function of an imaging system is given by a complex function P : R → C with the following constraints:

Fast Finite Element Method Using Multi-Step Mesh Process
This paper introduces a new method for accelerating current sluggish FEM and improving memory demand in FEM problems with high node resolution or bulky structures. Like most of the numerical methods, FEM results to a matrix equation which normally has huge dimension. Breaking the main matrix equation into several smaller size matrices, the solving procedure can be accelerated. For implementing ...
متن کاملFast Mux-based Adder with Low Delay and Low PDP
Adders, as one of the major components of digital computing systems, have a strong influence on their performance. There are various types of adders, each of which uses a different algorithm to do addition with a certain delay. In addition to low computational delay, minimizing power consumption is also a main priority in adder circuit design. In this paper, the proposed adder is divided into s...
