Attitude control of a satellite is performed by controlling two main parameters, angular speed and altitude. An inappropriate value for each of these parameters can lead the satellite to be lost in space or fall to the earth. This paper presents altitude and speed control of geostationary satellites by means of two controllers, the first one is a PID controller for regulating the altitude and the...
In this paper a method for segmentation of vessels in angiographic images is addressed. In this method for detecting the vessels in one angiographic frame, whole of angiographic frames in the sequence are utilized. For this purpose, firstly Hessian based vesselness filter is applied to the angiographic sequence to make discrimination between the vascular structures and the background. Afterward, the...
In the most of object tracking tasks dealing with partial occlusion is a challenging issue. Recently the use of color cue based on Monte Carlo tracking method and particle filtering is mostly considered to overcome the problem of partial occlusion and nonrigid motion. The proposed approach in this paper is based on using of sequential Monte Carlo and particle filtering for tracking. But in this method...
