We bring out a runway extraction method based on rotating projection in this paper, which is consisted of three steps, locating the Region of interest (ROI), edge extraction and line detection. Firstly we employed template matching to locate the ROI which contains the runway area. Then we use Sobel operator to extract edges. The rotating projection algorithm is proposed to seek the potential straights...
During the groups of decision making progress, according to the preference requirement that decision-makers emphasized and the vagueness of the evaluation information, this article describes how to use a method based on two-tuple linguistic to rank the weightiness of the competitive intelligence evaluation indexes and convert qualitative assessment to quantitative evaluation. Using this method, the...
We present quantitative mapping of large area graphene conductance by terahertz time-domain spectroscopy and micro four point probe. We observe a clear correlation between the techniques and identify the observed systematic differences to be directly related to imperfections of the graphene sheet on the length scale of several micrometers.
When coherent light is reflected off a rough surface, the scattered wavelets are perceived in the observation plane in the form of intensity. The strength of the intensity variations in the speckle pattern relies on the dynamics of the object as well as the optical system between the object and CCD (Charge-Coupled Device) detector. By advantages of digital speckle correlation method and statistical...
In order to determine the temporal points of action potentials in the neural signals and the correlation between neural signals, and to form an interface with the hardware system, a series of methods for signal denoising, pattern recognition, correlation analysis and primary signal coding are accepted. A set of toad's neural signals are used as the experimental object. The results show that in combination...
