Assessment of Noise Filtering Techniques on Color Images

Abstract: Digital images are used in different applications such as military, medicine, geoscience, ecology, etc. The quality of the images ensures accuracy and precision of results. The raw digital images we work with everyday are generally stored, transmitted and progressed in many ways which results in addition of noise to the image. Raw digital images carries the different types of noises during capture, due to various formats of storage, transmission, resolution of cameras. These noises affects the content, quality and creates the loss of necessary details .So it is essential to eliminate these noises with preserving the fine details of image quality for processing. This paper focuses on reviewing and analysing existing noise reduction filters by implementing them on color images degraded by the noise. Performance of noise filters are evaluated to find the suitability.
