چکیده
For the condition where star-point target detection and tracking real-time. This paper proposed a method of star-point target detection and tracking. The method includes two major steps, target detection and target tracking. In the detection stage, based on difference of inter-frame image in sequences, an adaptive threshold has designed. After morphological filtering and regional connectivity for segment image, using centroid extraction method to identify targets quickly. In the tracking stage, for the characteristic of star point target’s movement is linearity, the tracking method using least squares algorithm to estimate target’s moving trajectory. Based on recording target’s moving trajectory, an algorithm of estimating moving step length has proposed, it forecast targets’ centroid coordinate real-time. To track targets in accurate, a doubting grade checkout method has proposed too. The complete set of proposed methods used to apply in real star space sequence image. Extensive experiment results shows that, the methods are efficient, and it meets the requirement of detecting moving star-point target out of cluttered background real-time.

Nonexpansive mappings on complex C*-algebras and their fixed points
A normed space $mathfrak{X}$ is said to have the fixed point property, if for each nonexpansive mapping $T : E longrightarrow E $ on a nonempty bounded closed convex subset $ E $ of $ mathfrak{X} $ has a fixed point. In this paper, we first show that if $ X $ is a locally compact Hausdorff space then the following are equivalent: (i) $X$ is infinite set, (ii) $C_0(X)$ is infinite dimensional, (...

In this paper, the continuity of tracking a ground moving target using a Hexarotor is considered in the presence of sudden changes in direction, deceptive movements, temporary departure from the field of view (FOV) and changes in the height of the target. In this regard, a hierarchical guidance and control system for target tracking problem in an unknown environment and disturbances is proposed...

In this paper, we investigate the usage of machine learning in the detection and recognition of double stars. To do this, numerous images including one star and double stars are simulated. Then, 100 terms of Zernike expansion with random coefficients are considered as aberrations to impose on the aforementioned images. Also, a telescope with a specific aperture is simulated. In this work, two k...
