The analysis results showed that the strapdown approach will be faced to more error sources with sensor noise and motion disturbance. The simulation results verified this and indicated that the performance of the strapdown approach would not be as efficient as that of the direct approach.3. Analyzing the principle and error model of MEMS QRS gyro for the purpose of practical applications, the paper presented an autoregressive model for the gyro signal by means of time series theory.

To eliminate the disturbance of the noise (particularly the pulse noise and salt-and-pepper noise influence which causes by equipment and transmission) in image processing, a smooth operation is needed. In this paper we have analyzed several smooth operation methods and improve median filter method by a directional way to reduce the detail loss of smoothing process.
