In recent years, many vehicle detection algorithms have been proposed. However, a lot of challenges still remain. Local Binary Pattern (LBP) is one of the most popular texture descriptors which has shown its superiority in face recognition and pedestrian detection. But the original LBP pattern is sensitive to noise especially in flat region where gray levels change rarely. To solve this problem, Local...
This paper proposed a novel direct power control (DPC) scheme of a three-phase pulse width-modulated rectifier, which solves the problem that classical DPC can't adjust the active power and reactive power in a balanced way. Compared to the classical DPC, the proposed scheme considers the balance of the active and reactive power. When the difference between the active and reactive power tracking errors...
In this paper, the problem of balancing the noise removing and the image details preserving is considered. To remove noise adaptively, local dictionaries and sparse coding techniques are used. For a noised image patch, the local dictionary corresponding to it and the sparse coding technique are used to generate the sparse coding vector of the given patch. Then the noise of the given patch can be removed...
This paper mainly addressed the kinematics and dynamics simulation of the Slider-Crank mechanism. After proposing a mathematical model for the forward displacement of the slider-crank mechanism, the mathematical models for the forward velocity and acceleration of the slider-crank mechanism are constructed, respectively. According to the theory of statical equilibrium, the mathematical model for the...
