Abstract: Noise is an indispensable part of an imaging system. For having acceptable performance of reflectance estimation from digital signals, noise effects should be controlled. In this study a new method based on segmentation of noise is presented. Simulation and real experiments on four reflectance data sets showed that noise segmentation improves Wiener filter estimation method. However, oversegmentation can have reverse effect on the reflectance estimation results. [ABSTRACT FROM AUTHOR] |
