Image Noise Declining Approaches by Adopting Effective Filters

摘要

Digital Image Processing is one of the techniques which has a constant requirement in the world due to its immense applications in MRI scans, retaining old literature and enhancing the quality of images acquired from underwater or from the space. People have been working on image processing for years and have successfully classified the information which would lead us to fruitful results. This paper discusses about all the categories that form a major key to image processing and the outcomes of the various techniques that come under Digital Image Processing. It gives a clear description of different formats that a grayscale picture or a color picture could be classified into i.e., PNG, JPEG, GIF, TIFF, BMP. This paper also discusses about the different types of noises (Gaussian noise, salt& pepper noise, speckle noise etc.,) that distort the original picture in a minimalistic or in a large way. Multiple filters that can be applied to a picture to correct one or more errors are also specified with reference to the codes written in MATLAB. Respective outputs for the applied noise and the final images after clearance of noise using the filters are also exhibited in this journal.
