There are numerous noise reduction systems implemented for removal of noise and holding edge points over the images. The decision of denoising algorithm is based on the application and the kind of noise present on the image. Every strategy has its own uncertainties, favorable circumstances and confinements. The thought behind these methods is to obtain better results in terms of quality and expulsion of various noises. This paper proposes a hybrid method which applies frequency domain filters like Butterworth, Gaussian and Homomorphic filtering with Fourier transformations by applying a high pass channel to diminish the significance of low frequency segments and to denoising the images.
