Abstract: A novel digital video stabilisation approach that uses salient features and particle filter for global motion estimation is proposed in this paper. In this approach, the local salient features are first gained by the improved K-means clustering method using the features obtained from the Scale Invariant Feature Transform (SIFT) feature points extracted from the down-sampled images, and then the salient regions are located in the video frames. The trajectory of the features extracted from the salient regions is used to estimate global motion between frames. A new similarity function called SRMSE (Salient Region Mean Square Error) is proposed in particle filter framework to reduce the computational cost. Motion compensation yields stabilised video sequences using the estimates. Experimental results demonstrate that the proposed algorithm has good performance and improves the efficiency significantly.

Keywords: SIFT; scale invariant feature transform; k-means clustering; salient features; salient region; particle filter; video stabilisation; global motion estimation; motion compensation.
