  • Determining Intensity Similarity in Low-Light Conditions Using the Poisson-Quantization Noise Model
    Publication number: 20100303367
    Abstract: A Poisson-quantization noise model for modeling noise in low-light conditions is described. In one aspect, image information is received. A Poisson-quantization noise model is then generated from a Poisson noise model and a quantization noise model. Poisson-quantization noise is then estimated in the image information using the Poisson-quantization noise model.
    Type: Application
