Clustering integration method for image data of X-ray films
ActiveCN105139414AReduce the difficulty of observationAuxiliary diagnosisImage enhancementImage analysisForeign matterIntegration algorithm
The invention discloses a clustering integration method for the image data of X-ray films. The method comprises the steps of S01, pretreating the image of an X-ray film to obtain the data of the image; S02, obtaining a gray value (Gi, j) at each point of the image and storing obtained gray values in a gray value matrix G, wherein the gray value (Gi, j) represents the gray value of a point at the i row and the j column of the matrix; S03, conducting the clustering analysis and treatment on the gray value matrix G according to the k-means improved algorithm-based clustering integration algorithm or the hierarchical clustering-based improved algorithm; S04, conducting the integration operation according to the HGPA algorithm. According to the k-means improved algorithm-based clustering integration algorithm, the selection of k initial cluster centers is optimized. According to the hierarchical clustering-based improved algorithm, data are simplified during the data pretreating process. In this way, points of the same gray value in the matrix are divided in the same cluster, and the number of initial clusters is 256 at most. Therefore, the observation difficulty of X-ray films is lowered, and even exogenous foreign matters can be found out. As a result, the method facilitates the doctor diagnosing process.

The invention discloses a resistivity method annular observation system and method for a refuse landfill percolation channel, in the system, each annular monitoring unit comprises n electrodes, the n electrodes are uniformly buried in a rock-soil layer around a refuse landfill, and every two electrodes are connected through a power supply cable to form an annular shape of which the head and tail electrodes are not connected; the tail end electrode on each ring is connected with the first electrode on the external adjacent ring through a power supply cable; a visual data processing unit comprises a data converter, a data processing host and a computer; through cooperation of the annular monitoring unit and the visual data processing unit, inversion imaging processing is carried out on detection data, comprehensive comparative analysis is carried out on the detection data and a three-dimensional geologic model, and the position and the range of a refuse landfill percolation channel are delineated. According to the invention, the technical problems that the top electrode of the refuse landfill is difficult to arrange and the monitoring error of a conventional observation system is large are solved.

The invention discloses a metal-semiconductor composite structure, a SPPs excitation method and a preparation method. The structure sequentially comprises a transparent substrate, a multilayer dielectric film positioned on the transparent substrate, a semiconductor nanostructure positioned on the surface of the multilayer dielectric film, a transparent dielectric thin film for covering the semiconductor nanostructure, and a metal thin film positioned on the transparent dielectric thin film; the semiconductor nanostructure is used for forming defect of a nano scale on the surface of the metal thin film, and generating a fluorescence signal to excite the metal SPPs; the transparent substrate and the multi-layer dielectric film form a double-color-mirror substrate, and the double-color mirrorsubstrate is high in laser transmittance and high in fluorescence reflection; and the excitation method comprises the steps that the laser with relatively short wavelength penetrates through the double-color-mirror substrate and then is vertically incident on the semiconductor nanostructure, so as to excite the semiconductor nanostructure to generate a single-photon fluorescence signal with relatively long wavelength, and then the SPPs of the metal film is excited by the fluorescence signal. According to the invention, the excitation efficiency of the SPPs can be improved, and the detection difficulty and the detection cost of the SPPs can be lowered.
