Recovering high dynamic range radiance maps from in vivo fluorescence molecular imaging

A recent development in molecular imaging is in vivo fluorescence molecular imaging with near-infrared light, which has extraordinary significance in early diagnosis of the disease. This paper presents a method of recovering high dynamic range radiance maps at in vivo fluorescence molecular imaging technology. Use differently exposed photographs to recover the response curve of the imaging process, with the known curve, can fuse a single, high dynamic range radiance map whose pixel values are proportional to the true fluorescence signal values in the scene. Will contribute to quilitative and quatitative analysis, offer better observation, and get information much more accurate and true. Have great significance for analysis and diagnosis.
