大气光幕融合的去雾新方法
Novel Haze Removal Method Based on Atmospheric Veil Fusion
摘要
Abstract
In order to enhance contrast and detail information of haze image captured by the imaging system,a haze scene restoration algorithm based on atmospheric veil fusion is proposed.Firstly,the haze density distribution of distant area is roughly estimated based on the physical properties of the atmospheric veil in different depth and the optical reflectance imaging.Then,the global atmospheric veil is accurately estimated by using image fusion and filtering on the pixel level.Finally,the restored image is obtained through the inversion of the atmospheric scattering model,and the brightness and chroma of the images are adjusted via tone mapping.This method can avoid over defogging or halo artifacts and achieving a satisfactory restoration for better contrast and color fidelity.The experimental results yield that the proposed method is not only very simple and efficient,but also has robust scene adaptability and achieves real-time performance.关键词
