Digital image stabilization algorithm based on feature points tracking

A new algorithm is presented to solve the image rotation and translation of the digital image stabilization(DIS)system.The algorithm uses K-R method to acquire feature of the image,Similarity transform model is used in motion estimation.The model that has rotation and translation becomes another one which is only a rotation model rotating around the center.The complicacy and calculation of the model are reduced.The result shows that it has favorable stably effect.
