论文摘要
高动力范围（HDR）摄影涉及在不同的曝光设置中拍摄的一系列图像，以弥补数码相机的动态低范围，例如智能手机中使用的数字摄像机。在本文中，根据相机特征函数介绍了一种自动选择此类图像的曝光设置的方法。此外，基于优化公式和加权平均而引入了一种新的融合方法。这两种方法都是在智能手机平台上作为HDR应用程序实现的，以证明引入方法的实用性。提出了几种现有方法的比较结果，表明了引入解决方案的有效性以及计算效率。
High-dynamic-range (HDR) photography involves fusing a bracket of images taken at different exposure settings in order to compensate for the low dynamic range of digital cameras such as the ones used in smartphones. In this paper, a method for automatically selecting the exposure settings of such images is introduced based on the camera characteristic function. In addition, a new fusion method is introduced based on an optimization formulation and weighted averaging. Both of these methods are implemented on a smartphone platform as an HDR app to demonstrate the practicality of the introduced methods. Comparison results with several existing methods are presented indicating the effectiveness as well as the computational efficiency of the introduced solution.
