Abstract

The major objective of the electronic image stabilization algorithm is to eliminate the flutter in the image sequences due to camera shakes. The relationship between image shaking and camera motion is deduced based imaging model. The physical cause of image transformation models is indicated. A self-adaptive multi-model electronic image stabilization algorithm is proposed, which can choose appropriate image transformation model and corresponding motion estimation method automatically, by computing the shaking amplitude of image sequences when camera is working. The experimental result shows that this algorithm can achieve high precision stabilization to image sequences and enhance the abilities of applicability and real-time of electronic image stabilization algorithm.
