Abstract:

本发明属于图像处理领域,涉及基于多尺度WLS滤波的雾天图像恢复方法。所述方法包括:根据暗通道先验原理估计大气光照强度A;结合得到的大气光照强度A的值,对图像I进行白平衡,并简化大气散射模型;根据雾天环境的物理属性,对大气耗散函数V进行粗估计,得到;采用多尺度WLS滤波对大气耗散函数进行细估计,得到Vi;结合获得的多尺度大气耗散函数Vi,根据简化大气散射模型恢复雾天图像为理想天气下的图像Ri;结合获得的多尺度恢复图像Ri,采用色调映射算法调整图像动态范围,进行可视度的提升,得到最终结果R。本发明能够有效提高雾天图像的对比度与清晰度,具有计算复杂度较低、执行效率较强等优点。
