In this paper a novel method for effectively denoising the extremely corrupted image by fixed value impulse noise using robust estimation based filter is proposed. The proposed algorithm classifies the pixels of localized window in to " corrupted " or " uncorrupted " and removes only corrupted pixels by robust estimation or by mean of the processed(More)
The paper explores a new technique for improving dynamic range of instrumentation amplifier which is most commonly used signal processing device. The method which improves the dynamic range by blocking undesirable input DC offset voltages without use of conventional RC components [1] is free from the errors produced due to their finite tolerances which(More)
