Bassey 1 Julie Ogbulezie 1 Department of Physics, University of Calabar, Nigeria Noise is an ever present phenomenon while dealing with recording devices, be it digital or analog, be it specks in images or background hiss in music recordings. Therefore, this paper aims at ways of reducing the effects of these forms of noise on image and sound files that can be compressed and sent through a communication channel. This noise reduction mechanism is represented in the form of algorithms and combined with data compression to minimize the effects of noise, while images and sounds are transmitted with their original content undistorted. http://pubs.sciepub.com/dt/2/1/2/dt-2-1-2.pdf data compression noise reduction compression algorithm image smoothening quantization
