摘要：
The present paper describes noise detection and reduction for an imaging system by a method of autocorrelation of pixel data change as a function of time. The random noise level could be detected for each pixel using the proposed method. An algorithm proposed for determining the noise level, and calculating the pixel value by the autocorrelation function value reduced the calculation cost. The proposed method is effective for reducing noise in real time image processing.
