Adaptive enhancement and noise reduction in very low light-level video
(2007) IEEE 11th International Conference on Computer Vision, 2007. ICCV 2007 p.1395-1402- Abstract
- A general methodology for noise reduction and contrast enhancement in very noisy image data with low dynamic range is presented. Video footage recorded in very dim light is especially targeted. Smoothing kernels that automatically adapt to the local spatio-temporal intensity structure in the
image sequences are constructed in order to preserve and enhance fine spatial detail and prevent motion blur. In color image data, the chromaticity is restored and demosaicing of raw RGB input data is performed simultaneously with the noise reduction. The method is very general, contains few user-defined parameters and has been developed for efficient
parallel computation using a GPU. The technique has been applied to image sequences...

animals, particularly the spatial and temporal visual summation that allows these animals to see in dim light. (Less)
