AUTOMATIC REDUCTION OF NOISE IN DATA ACQUIRED BY DIGITAL CAMERAS
F. Russo, A. Lazzari
Abstract:
A technique for automatic noise correction in color images acquired by digital cameras is presented. The proposed method deals with the R, G and B components of the image and adopts a nonlinear approach in order to perform a very accurate restoration of the data. The optimal parameters that define the key filtering action are obtained by an automatic procedure that independently operates on each channel. Experimental results show that the method is very effective and well suited to correct the typical noise increase that occurs when high sensitivity is chosen during image acquisition.
