Abstract

The proposed Fuzzy Logic and Distance Measure based Adaptive Filter (FDMA) uses the principles of fuzzy logic and distance measure for the detection and correction of fixed-value impulse noise, respectively. This filter, in the noise detection phase, classifies the pixel of the corrupted image either as uncorrupted or corrupted ones, using fuzzy logic and statistical measures and thereby constructs a flag matrix. In the noise correction phase, the intensity of each corrupted pixel is replaced by an estimated intensity value, computed using its uncorrupted neighbouring pixel, lying within Minimum Euclidian Distance. The noise suppression capability of this filter is quantitatively measured using Peak Signal to Noise Ratio, Mean Structural Similarity Index Matrix and Coefficient of Correlation values. Additionally, the merit of this filter is endorsed by Human Visual Perception of the restored images. The noise restoration ability of FDMA is confirmed to outperform the reported filters. This filter can seamlessly be employed in the application domain wherein fixed-value impulse noise is the primary cause for quality degradation.
