Particle probability hypothesis density filtering has become a tractable means for multi-target tracking due to its capability of handling an unknown and time-varying number of targets in non-linear or non-Gaussian system in the presence of clutter and missing measurements. However, it is time-consuming because hundreds of thousands of particles are required to reach a satisfactory tracking accuracy,...
Current digital devices lack the ability to adapt to various lighting conditions, and this makes image color auto adjustment increasingly important. In this paper, we present a simple and effective progressive image color neutralization approach to adjust the image bright region, dark region and mid region independently. First we neutralize the bright region and dark region based on single representative...
In response to the roller bearing fault of the engineering vehicle, the excellent characteristics of time-frequency of wavelet packet is used to decompose the fault signal. Then we extract the necessary of the fault signals. Finally, we carry out the recognition of fault types using multi-class support vector machine and dynamic clustering algorithm brought forward in the paper. It is such a algorithm...
