Universal Demosaicking of Color Filter Arrays [PDF]

open access: yesIEEE Transactions on Image Processing, 2016
A large number of color filter arrays (CFAs), periodic or aperiodic, have been proposed. To reconstruct images from all different CFAs and compare their imaging quality, a universal demosaicking method is needed.

The Universality of the Kalman Filter

open access: yes, 2021
The universality of the Kalman filtering can be found in the control theory. The Kalman filter has found its applications in sophisticated autonomous systems and smart products, which are attributed to its realization in a single complex chip. In this chapter, considering the Kalman filter from the perspective of conditional characteristic function ...

Synthesis of Cascadable DDCC-Based Universal Filter Using NAM

open access: yesApplied Sciences, 2015
A novel systematic approach for synthesizing DDCC-based voltage-mode biquadratic universal filters is proposed. The DDCCs are described by infinity-variables’ models of nullor-mirror elements which can be used in the nodal admittance matrix expansion ...

Universal Filtering Via Hidden Markov Modeling [PDF]

open access: yesIEEE Transactions on Information Theory, 2008
The problem of discrete universal filtering, in which the components of a discrete signal emitted by an unknown source and corrupted by a known DMC are to be causally estimated, is considered. A family of filters are derived, and are shown to be universally asymptotically optimal in the sense of achieving the optimum filtering performance when the ...

MIXED MODE UNIVERSAL FILTER

open access: yesJournal of Circuits, Systems and Computers, 2013
The configuration with electronic tunable characteristics that can work in mixed mode may be useful from IC realization viewpoint and application adaptability. This paper proposes an electronically tunable mixed mode universal filter based on multiple output current controlled current conveyor (MOCCCII) and this single topology without any alteration ...
