A Decision based unsymmetrical trimmed variants is proposed for the elimination of unequal probability salt and pepper noise in gray scale images. The proposed algorithm replaces the corrupted pixels with unsymmetrical trimmed median or midpoint based on the noisy pixels in the current processing window. The proposed algorithm shows excellent noise(More)
A novel algorithm is proposed for the restoration of images corrupted by low density impulse noise, also known as salt and pepper noise. The new algorithm significantly produces better image quality than standard median filter (SMF), adaptive median filters (AMF) and threshold decomposition filter (TDF). The proposed algorithm (PA) is tested on different(More)
In this paper, new area minimized architecture is proposed for median filters based on modified decomposition algorithm. The modified decomposition replaces the complexity of existing threshold decomposition algorithm such as complex comparators. The proposed algorithm works in two stages, decomposition and recombination. The proposed algorithm removes the(More)
A Decision based restoration algorithm using Unsymmetrical Trimmed Mode filter for gray scale images that are corrupted by salt and pepper noise is proposed. The processed pixel is examined for 0 or 255; if checked pixel is equal to 0 or 255, then it is considered as noisy pixel else not noisy. If the pixel is noisy and all the four neighbors are noisy then(More)
UPS Systems are primarily related on battery reliableness which serves as a vital segment for framework unwavering quality. One of the vital parameters that are obliged to guarantee safe charging and discharging is SOC. As the battery SOC is an essential parameter, which mirrors the battery execution, so exact estimation of SOC can't just secure battery,(More)
This work aims a cascaded decision based filter for the removal of high density in image and video is proposed. The proposed scheme operates in two levels. First level is a decision based median filter and the later employs a decision based unsymmetrical trimmed variants. In the first stage the corrupted pixels are found and replaced by the median of the(More)
