Highly Precise Noise Filter for Time-Series Data

Time-Series data such as motion data has several types of noise in general. 　Various nonlinear filters have been proposed in image processing for noise reduction. However, still it is difficult to balance both high precise noise reduction and not disrupting data portion which is important to keep original data structure. 　This invention is a kind of non-linear special filtering, named Structure-aware Temporal Bilateral Filter(SATBF). SATBF enables highly precise noise reduction without disrupting essential structure of the original data.
