A method for reliability estimation of temporal noise estimation in a sequence of video frames. The temporal local differences from a difference between a previous frame and a next frame in the sequence of frames is determined. A distribution of the temporal local difference is determined. Characteristics values of the distribution are determined. The characteristics values are compared to the thresholds to obtain an indication of the reliability of the temporal noise estimation. If the estimated noise variance is determined as not reliable, it will be discarded and the previous estimated reliable noise variance will be used instead indicating the noise level of the current frame.
