Noise in digital image processing is a disorder caused by deviations of the data received. There are three types of noise, Additive, Gaussian and Speckle. Currently, there are many methods for reducing noise in digital images. One method that can be used for reducing noise is convolution method, which consists of Low Pass Filter, High Pass Filter, Median Filter, Mean Filter and Gaussian Filter. This research will analyze an output by applying the convolution method for noise reduction with various parameters such as histogram, Timing- Run calculation and SNR calculation. Noise reduction will be imposed on the three types of noise.
