HDR (High Dynamic Range) imaging is a technique that combines multiple photos taken at different exposures to create an image that preserves both bright and dark areas, and OpenCV's photo module supports it. HDR images are created with the Debevec and Robertson methods, which estimate the camera response curve, or the Mertens method, which merges directly without a response curve, and tone mapping is done with the Tonemap family of classes so the result can be shown on a display. Shaking between input images is aligned with AlignMTB.
