JIMENEZ HERNANDEZ, Hugo  e  SALAS RODRIGUEZ, Joaquín. An Strategy for the Dynamic Selection of Features Applied to the Stabilization of Image Sequences. Comp. y Sist. [online]. 2011, vol.14, n.4, pp. 351-363. ISSN 1405-5546.

This work introduces an algorithm to discriminate between either moving or static features of a given scene as observed from a fixed camera, which is under the effects of vibration,. In our strategy, we select the features minimizing the registration error from one image to the next one. The process discards the features corresponding to moving objects and untrackable regions. The algorithm is applied to the task of stabilizing an image sequence. In our experiments, we benchmark our approach with several images sequences and match the results with a randomized strategy known as RANSAC.
