Abstract
An overview is given of the important aspects of feature-based motion analysis, especially with regard to more than two frames. These topics include some history of feature-based techniques, reasons to use feature-based techniques and longer sequences, applications to real motion sequences, and some directions for this kind of research. It is pointed out that feature-based motion analysis involves work on several subproblems such as feature extraction, feature matching, motion estimation, and the use of the motion estimates. The final use of the motion analysis can be for target tracking 3D reconstruction and improved matching results. Real-world motion analysis programs must assume that the computed feature matches are only good enough for motion estimation, and not perfect. Feature-based systems offer many ways to achieve good performance with real-world data.Keywords
