Median filters commonly used in image processing applications for the removal of impulse noise. Over the years so many median filters such as are separable median filters, recursive median filters, weighted median filters, max-median filters and multistage median filters were developed. Sorting networks are of major concern for real time hardware implementation of filters. Sorting is a computationally...
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 need for 0 to 255 threshold gray levels for...
