On the basis of analysing the compression and unscompression algorithm of bitmap,an improved algorithm is presented,which is proved to be effective and have higher compress rate,and the uncompressed image is lossless.

Development of X-ray image guided radiofrequency catheter ablation system;

Comparison of two image navigation algorithms based on micro aerial vehicle

Synchronously system security and malfunction diagnosis of the robot, master-slave telecontrol, visual reality and image navigation are thoroughly studied.

To satisfy the high accuracy of attitude determination for three-axis stabilized geostationary meteorological sat- ellite image navigation,a new approach combined gyro with star sensors is proposed,and a real-time algorithm for aiti- tude estimation combined predictive filter and extended Kalman filter is designed.

It is a key technique of C-arm-based image-guided surgical system to detect landmarks and extract their data in fluoroscopic images.
