摘要:
A method employing a statistic means to test whether or not luminance signals around a point of interest are distributed according to the same probability distribution with respect to luminance signals of respective pixels constituting the image; determining a range where the same probability distribution can be regarded as being satisfied, estimating the true luminance value of the point of interest by using the luminance data of the range. Especially when the image signals are faint to such an extent that the intensity of the luminance signal is based on the Poisson distribution, it is effective to perform a smoothing processing for each of the probability distributions of the signals and the noises by a test of a uniformity of the Poisson distribution, enabling a clear and denoised image to be obtained.
