Dese population estimation method and system based on multi-feature fusion

The invention provides a dense population estimation method and a system based on multi-feature fusion. The method comprises the following steps: partitioning an image into N equal sub-blocks; performing hierarchical background modeling on the image by using a method based on a CSLBP (Center-Symmetric Local Binary Pattern) histogram texture model and mixture Gaussian background modeling, extracting the foreground area of each sub-block subjected to perspective correction, detecting the edge density of each sub-block in combination with an improved Sobel edge detection operator, and extracting four important texture feature vectors in different directions for describing image texture features in combination with CSLBP transform and a gray-level co-occurrence matrix; performing dimension reduction processing on the extracted population foreground partition feature vectors and texture feature vectors through main component analysis; inputting the dimension-reduced feature vectors into an input layer of a nerve network model, and acquiring the population estimation of each sub-block through an output layer; adding to obtain the total population. The dense population estimation method and system have high accuracy and high robustness, and a good effect is achieved in the population counting experiment of subway station monitoring videos.

Method for collecting spatial population distribution in real time on basis of mobile phone big data and realizing large passenger flow early warning

The invention aims at providing a method for collecting spatial population distribution in real time on the basis of mobile phone big data and realizing large passenger flow early warning. The method is characterized by comprising the following steps of obtaining real-time mobile phone big data from a mobile phone communication operator at each statistics moment; dividing a target region into different space regions; at the current statistics moment, mapping the latest space position of each EPID (Electronic Portal Imaging Device) obtained in the first step to each space region of the target region; and obtaining the real population size (the distribution condition of the total population in the whole target region) in each space region at the current statistics moment. The method has the advantages that the sufficient relying on the existing mobile phone big data resources is realized; the continuous encrypted position information of the existing mass anonymous mobile phone users in the mobile communication network is used; the low-cost high-frequency and automatic implementation can be realized; and the popularization distribution data in a large-range urban space range can be continuously obtained in a fast deploying way.

Method for estimating earthquake disaster casualty population and computer readable medium

The invention discloses a method for constructing an earthquake disaster casualty population estimation model. The method includes a step of acquiring a plurality of historical seismic data includingmagnitudes of earthquakes, epicenters of the earthquakes, earthquake years, and earthquake casualty population, a step of determining the affection area of an earthquake of this time according to theearthquake magnitude and the epicenter of the earthquake, a step of determining a total population of the earthquake affection area according to population distribution data of the earthquake affection area, a step of obtaining a population casualty rate of the earthquake according to the earthquake casualty population and the total population of the earthquake affection area, and a step of establishing the earthquake disaster casualty population estimation mode characterized by an earthquake magnitude according to the magnitudes of historical earthquakes and corresponding earthquake population casualty rates. By using the model, the scope and casualty population of an earthquake disaster affection area can be quickly calculated at the first time of obtaining the earthquake magnitude, anda basis is provided for corresponding rescue measures through the rapid evaluation of a casualty after an earthquake disaster.

Chinese traditional medicine for treating chronic pharyngitis and its preparation

The present invention relates to a Chinese traditional medicine for treating throat diseases of chronic laryngeal yin symptoms and method for making same. According to related iatrology clinical reports, the number of patients suffering from various chronic throat diseases is 12% of the total population in china. At the present time, in china, there are few pure Chinese traditional medicine formulation medicines for treating clinically throat diseases, especially for treating chronic laryngeal yin (vocal nodules, sound tape polypi, mucous membrane thickening) and the like. According to the present invention, pinellia tuber, kernels of peach, rouge vegetal for promoting flow of qi and blood circulation, eliminating the silt and vein relaxing, fritillaria and chicken's gizzard-skin for liquefying the phlegm and breaking the mass, are used as the principal agents; together with flower of honeysuckle, dandelion for preventing phlegm silt and avoiding the fire change of yang, ophiopogon root for nourishing yin and moistening dryness, oroxylum indicum for guiding jing and relieving depression; to reach the functions of silt eliminating and phlegm degeneration. Thus, the present invention has remarkable curative effects, can exert curative effects to more degree, with short curative effect periodic time, fast effects, high strengthening rate, without clinical toxic and side effects and recurrences.

High Strength Steel and Production Method

The present invention provides a cold-rolled and annealed steel sheet of thickness between 0.7 mm and 2 mm, mechanical strength ranging from 1180 MPa to 1320 MPa, wherein the hole expansion ratio Ac % is greater than 20% and the bending angle is greater than or equal to 40°. The chemical composition includes, the contents being expressed as weight percent: 0.09%≤C≤0.11%, 2.6%≤Mn≤2.8%, 0.20%≤Si≤0.55%, 0.25%≤Cr<0.5%, 0.025%≤Ti≤0.040%, 0.0015%≤B≤0.0025%, 0.005%≤Al≤0.18%, 0.08%≤Mo≤0.15%, 0.020%≤Nb≤0.040%, 0.002%≤N≤0.007%, 0.0005%≤S≤0.005%, 0.001%≤P≤0.020%, Ca≤0.003%, the remainder being iron and inevitable impurities resulting from processing. The sheet has a microstructure including martensite or lower bainite. A sum of the surface fractions of martensite and lower is between 40% and 70%, from 15% to 45% of the surface fraction is low-carbide bainite, from 5% to less than 20% of the surface fraction is ferrite, the non-recrystallized ferrite fraction relative to the total ferrite fraction is less than 15%, and less than 5% of the surface fraction of residual austenite is in the form of islands. The fraction of former austenitic grains in which the size is less than at least one micrometer represents 40% to 60% of the total population of the former austenitic grains.

Chinese traditional medicine for treating laryngopharyngeal paresthesia and its preparation

The present invention relates to a Chinese traditional medicine for treating laryngopharyngeal paresthesia and method for making same. According to related iatrology clinical reports, the number of patients suffering from various throat diseases is 12% of the total population in china. At the present time, the most of the medicines for treating throat inflammation in china are a drug for treating a plurality of diseases, and the curative effect is not very ideal, especially medicines for treating chronic laryngeal yin, laryngopharyngeal paresthesia, sound tape thickening symptoms and the like exhibits tiny tiny curative effects. According to the medicine composing prescription in accordance with the present invention, pinellia tuber, Arisaema cum bile for dispersing pathogenic wind and resolving phlegm, poria cocos wolf which is sweet and light and used for excreting dampness to cultivate the spleen, perilla stem, magnolia bark and citrus aurantium for elevation and subsidence of the functional activities of qi, are used as the principal agents; together with amomum fruit, areca-nut, medicated leaven for activating the spleen and harmonizing the function of the stomach, oroxylum indicum for guiding jing and relieving depression, cicada-shell for relieving sore-throat and spasmolysis; then the medicine composing prescription has the functions of functional activities of qi smoothing, phlegm dehumidificaiting, throat benefiting and the like.Thus, the medicine has remarkable curative effects, can exert curative effects to more degree, with short curative effect periodic time, fast effects, high strengthening rate, without clinical toxic and side effects and recurrences.
