Abstract: Among the many applications of image processing, which are being investigated extensively by researchers at present, noise removal from digital images is one of the most interesting. The criticality of noise removal from digital images has increased in recent years with the advent of modern high-speed communication networks. Multimedia processing has emerged as a major thrust area due to the availability of high bandwidth for users. The current paper proposes an effective novel method for de-noising digital images. Types of noise commonly affecting digital images, and standard techniques used to de-noise digital images are discussed in brief, before demonstrating the superiority of the proposed median filtering method. The method is found to be more effective than many of the standard methods available.
