Novel Color Image Denoising Method Based on Fractional-Order Partial Differential Equation and CB Model
摘要
Abstract
Combing fractional-order differential theory with Chromaticity-Brightness(CB) model ,a novel image denois-ing model was proposed ,which was based on fractional-order partial differential equation and CB model .Firstly ,a color im-age was decomposed into chromaticity component and brightness component .Secondly ,fractional-order differential model was used for brightness component .For chromaticity component ,Lagrange multipliers method was used and an auxiliary variable was added to approximate the chromaticity .Thirdly ,the retorted image was got by multiplying the recovered chro-maticity with recovered brightness .Finally ,it proved the validity of the proposed model through the experiment .关键词
