Stack filters are a special case of non-linear filters. They have a good performance for filtering images with different types of noise while preserving edges and details. A stack filter decomposes an input image into several binary images according to a set of thresholds. Each binary image is filtered by a Boolean function. The Boolean function that characterizes an adaptive stack filter is op...

We propose a scalable extension of the H.264/AVC video coding standard. To achieve an efficient scalable bit-stream representation of a video sequence, the temporal dependencies between pictures are exploited by using an open-loop subband approach. The related temporal analysis-synthesis filter bank structure is generalized to facilitate an adaptive block-based choice between the motion-compens...

We present in this paper a uni ed processing for Real, Integer and Boolean Constraints based on a general narrowing algorithm which applies to any n-ary relation on <. The basic idea is to de ne, for every such relation , a narrowing function ! based on the approximation of by a Cartesian product of intervals whose bounds are oating point numbers. We then focus on non-convex relations and estab...

In this paper, an energy-efficient estimation and detection problem is formulated for low-power digital filtering. Building on the soft digital signal processing technique proposed by Hegde et al., that combines algorithmic noise tolerance (ANT) and voltage scaling to reduce power, the proposed minimum power soft error cancellation (MP-SEC) technique detects, estimates and corrects transient er...

Feedback Shift Registers (LFSR) is presented here. In this method, shift register structure used for polynomial modular division is combined with LFSR keystream generator to yield a new keystream generator with much higher periodicity. Security is brought into this structure by using the Boolean function to combine state bits of the LFSR keystream generator and taking the output through the Boo...

In this paper the concept of an $Omega$- Almost Boolean ring is introduced and illistrated how a sheaf of algebras can be constructed from an $Omega$- Almost Boolean ring over a locally Boolean space.

This work presents a non-invasive method to determine the glucose levels in blood samples using planar Yagi-Uda antenna and novel microstrip filter. The proposed operates at 5.5 GHz exhibiting uni-directional pattern giving maximum gain of 6.74 dBi operating band. A commercially available low-cost FR-4 substrate dimensions 30 mm×40 mm×1.6 mm is used as dielectric substrate. finger phantom resem...

Soft errors, due to cosmic radiations, are the major reliability barrier for VLSI designs. The vulnerability of such systems to soft errors grows exponentially with technology scaling. To meet reliability constraints in a cost-effective way, it is critical to assess soft error reliability parameters in early design stage to optimize reliability in the entire design cycle. Unlike soft error mode...
