曝光融合
介绍
曝光融合是一种从一组多重曝光图像中创建具有最佳细节的单个图像的技术。正如Tom Mertens等人所开发的那样,所提出的算法计算了相关的质量度量;对比度、饱和度和曝光良好。然后将这些测量组合在一起以创建一个权重图,用于将每个多重曝光图像混合到具有最佳曝光的单个图像中。

描述
正如Tom Mertens[1]所开发的那样,曝光融合算法计算相关的图像质量测量;对比度、饱和度和曝光良好。然后将这些测量组合在一起以创建一个权重图,用于将每个多重曝光图像混合到具有最佳曝光的单个图像中。在摄影过程中寻找最佳曝光设置时,对曝光融合的需求增加。由于这需要掌握曝光三角形,这很困难,需要权衡,并且对于某些场景完全不切实际,因此已经开发了诸如高动态测距(HDR)和曝光融合之类的技术来获得理想的最终图像。然而,与HDR不同的是,曝光融合不需要计算相机响应曲线或色调映射。
