| Abstract: | An adaptive filtering algorithm is developed to reduce the noise in image sequences, which is based on detecting motion in image sequences. This algorithm firstly judges whether there is motion in image sequences, and then accumulatively filters using the common info in image sequences. In the meantime, the overlapped image caused by the displacement of sub-pixels can be avoided to achieve the bettering of images. The noise variance equation is demonstrated here and is used to sort out the accumulated data of the video images. The filtering effects under different thresholds are also discussed here. |
