A digital image stabilization algorithm for image sequence based on particle filter was present. Firstly
the corners are extracted using improved sobel operator
then the mapping relationship is established between ima- ges and global motion vectors are obtained adopting least-squares solution using affine transformation model. Las- tly
correctional vectors are acquired using particle filtering and video frames are correctly adjusted. Experimental results show the stabilization algorithm is effective and robust. The correct vectors of camera are reserved and noi- se is eliminated.
