Cooperative spectrum sensing can improve sensing capability of the system. But in a system which owns channels of different protection levels, it will bring bad effects to detection performance when using a single sensing algorithm and data fusing rule in different channels of this system. Therefore this paper proposes a cooperative sensing algorithm, which is based on policy database to select different...
Harris corner detection is a classic corner detection algorithm, but using Gaussian smoothing filter, there is phenomenon of corner information missing and corner migration. In this paper, to have a data-fitting and low-pass characteristics of B-spline function introduced into the algorithm, construct a new filter, while introducing the idea of image sub-block and the excluding neighboring points...
Dendritic spines play an essential role in the central nervous system. Recent experiments have revealed that neuron functional properties are highly correlated with the statistical and morphological changes of the dendritic spines. In this paper, we propose a new multi scale approach for detecting dendritic spines in a 2D Maximum Intensity Projection (MIP) image of the 3D neuron data stacks collected...
