Multi-Frame Noise Reduction using noise robust Motion Detection

Abstract

Currently, a surveillance camera which I can take a motion in the low illumination environment is required. There is the noise reduction algorithm using multi images. It is possible to reduce noise in the low illumination environment without object blurring. But, the conventional technique has a problem misrecognizing a noise as a moving object under the environment with much quantity of noise. Therefore we propose the noise reduction algorithm using noise robust motion detection. This algorithm performs motion detection from input image and delayed image and change the noise reduction amount according to the motion detection amount. As a result, proposed method reduces noise about half compared with conventional method.
