Abstract
Image processing is a signal processing technique used in various fields like medical and education. While capturing the image from surveillance cameras the chances of obtaining a perfect picture are scanty i.e. the noise maybe introduced in the image. This noise enters in the image due to medium, environment, interface circuitry etc. Images can also contain a lot of deteriorations viz. uneven illumination, blur,low resolution,perspective distortion, smear etc. To remove the noise various techniques and filters are provided in the field of image processing. Image filtering can also be used to calculate the probability density function. By using this function clarity within the image can be introduced. We have myriad techniques in order to embellish the image but reviews of some specific techniques which are optimal in nature are discussed. In our proposed paper we are reviewing all the techniques which can be used to overcome the noise in the image.
