Periodic noise degrades the image quality by overlaying similar patterns. This noise
appears as peaks in the image spectrum. In this research, a method based on fuzzy …

Given the grid features of digital images, a direct relation with cellular automata can be
established with transition rules based on information of the cells in the grid. This document …

Remote detection of landmarks for navigation of mobile autonomous robots in the absence
of GPS is carried out by low-power radars, ultrasonic and laser rangefinders, night vision …

Periodic noise has a global impact in spatial domain and can only be removed using
frequency domain analysis. In this paper, a novel frequency domain technique is proposed …

Digital image processing is playing a key role in variety of application areas like medical
