We would like to welcome you all to the - tenth volume - second issue - of The Mediterranean Journal of Electronics and Communications. This issue of the journal, comprising of five papers, is dedicated to the latest research work being done in wireless networks, optical communications, and image processing. The first paper by Jena deals with impulse noise removal process from digital images is which is one of the most important concerns in digital image processing. Impulsive noise may occur during image acquisition, transmission or storage which is often not possible to avoid in practical situations. The noise should be removed in such a way that important information of image should be preserved. The restoration process of many known algorithms are effective for the images corrupted by random valued impulse noise, but not efficient especially for real-time applications. In this paper, authors propose an efficient impulse noise suppression technique using optimal direction based noised detection followed by non-local mean filtering. Extensive simulations show that the proposed technique has superior performance in terms of both visual quality and quantitative measurement.
