Abstract
This paper proposes a two-phase scheme for removing salt-and-pepper impulse noise. In the first
phase, an adaptive median filter is used to identify pixels which are likely to be contaminated by noise
(noise candidates). In the second phase, the image is restored using a specialized regularization method
that applies only to those selected noise candidates. In terms of edge preservation and noise suppression,
our restored images show a significant improvement compared to those restored by using just nonlinear
filters or r ....etc

Adaptive bilateral filter for sharpness enhancement and noise removal
Presented By:
Zhang B, Allebach JP.
Texas Instruments, Inc, TX 75243, USA.
Abstract
In this paper, we present the adaptive bilateral filter (ABF) for sharpness enhancement and noise removal. The ABF sharpens an image by increasing the slope of the edges without producing overshoot or undershoot. It is an approach to sharpness enhancement that is fundamentally different from the unsharp mask (USM). This new approach to slope restoration also differs significantl ....etc

A LOW COST FIELD USABLE PORTABLE DIGITAL GRAIN MOISTURE
METER WITH DIRECT DISPLAY OF MOISTURE (%)

ABSTRACT:-
Moisture content of grain is one of the important parameters always considered
when deciding the quality and price of grain, at the stage of harvesting, storage, processing and
marketing. Grain having excess moisture content, if stored for long duration, will spoil due to
insect/fungus infestation. Portable, field usable, and easy-to-use direct moisture (%) display Grain
Moisture Meter is a necessi ....etc

A New Delayless Subband Adaptive Filtering Algorithm for Active Noise Control Systems
Abstract
Subband adaptive filtering (SAF) techniques play aprominent role in designing active noise control (ANC) systems.They reduce the computational complexity of ANC algorithms,particularly, when the acoustic noise is a broadband signal and thesystem models have long impulse responses. In the commonly useduniform-discrete Fourier transform (DFT) -modulated (UDFTM)filter banks, increasing the number of subbands decreases thecomputational burden bu ....etc
