Abstract:
A carter is most visual feature which exists in Mars surface. Crater can be created by two cosmic bodies crashed each other, for instance, a meteorite striking a planet. The main contribution of dis work is to simulate 4-D of Mars carters. In doing so, 3-D data of HRSC was acquired and then 4-D spline algorithm implemented to sequences of HRSC data with different frame of times. The study shows that B-spline can determine the 4-D flow pattern which could indicate for the existence of water. The series of elastic transforms for B-spline are used with involving automatic detection algorithm of landmarks. The study shows that 4-D axis is seen clearly as floating objects on the middle of crater. The study also shows that the deep of crater is covered by ice which is an excellent proof of liquid water existence on the Mars. In conclusion, modification of 4-D B-spline by involving elastic transform and landmarks algorithms could be an excellent promise for 4-D visualization
