Paper Abstract

The piezoelectric gyroscope is regarded as an important device which measures the motion vector among frames of the dynamic image sequences; precision of its output signal directly determines the precision of the image stabilization. Analyzing the characteristics of output noise of gyroscope, it is available for us to suppress the output noise by applying the median filtering algorithm and wavelet transformation. The experiment results of electronic image stabilization have shown that this method can improve the precision of motion vector estimation effectively.
