We compared two different cosmic ray location algorithms—Laplace and GUO methods. They are useful for a two-dimensional optical fiber to position on the cosmic ray spectrum image. Removing the cosmic rays belongs to the category of the pretreatment. The pretreatment method for two-dimensional optical fiber spectral image is important, it effects the subsequent stellar spectral processing. Cosmic ray...
It is conductive to discover the fire or smoke leakage in the monitor region that detecting the smoke area clearly. Firstly, an adaptive LOG algorithm of smoke detection based on energy difference is proposed by the paper. After detecting the enhancement smoke area by energy difference between frames, dynamic accumulation, filtering and extracting smoke leakage position will be performed. The experiment...
A 1-D RHT method based on symmetry point searching for ellipse detection is presented in this paper. In this method, three undetermined parameters of the candidate ellipse would be determined by two axisymmetric points and one central symmetry point. The acquisition of the group of symmetric points mentioned above could complete the ellipse detection by using only one dimension accumulation array...
