摘要：By adapting to lights in any viewing condition, the human visualsystem can capture a wide dynamic range of irradiance (about 14orders in log unit), while the dynamic range of CCD or CMOSsensors in most of today’s cameras does not cover the perceptionalrange of real scenes. It is important in many applications to capturea wide range of irradiance of natural scene and store it in eachpixel. In the application of CG, a High Dynamic Range Image(HDRI) is widely used for high quality rendering with imagebased lighting. Nowadays HDR imaging technologies have beendeveloped and some high dynamic range sensors are commerciallyavailable. They are used for in-vehicle cameras, surveillance innight vision, and camera-guided aircraft docking high contrastphoto development, robot vision etc. In the last decade, to capturethe HDRI, many techniques have been proposed based on themultiple-exposure principle, in which the HDRI is constructed bymerging some photographs shot with multiple exposures. Manyof the techniques assume that a scene is static during takingphotographs.
