59 results about "Type - attribute" patented technology

Attributes can be classified as identifiers or descriptors. Identifiers, more commonly called keys or key attributes uniquely identify an instance of an entity. If such an attribute doesn't exist naturally, a new attribute is defined for that purpose, for example an ID number or code.

Method for identifying airport target in remote sensing image by fusing scene information and depth features

The invention provides a method for identifying an airport target in a remote sensing image by fusing scene information and depth features. The method comprises the steps of generating target candidate boxes of the airport on the image in a sliding window manner according to a plurality of preset sizes; constructing a deep convolutional neural network feature extractor, adding corresponding internal window and context window for each target candidate box for realizing learning and extraction of features, internal features and context features of regional images of the candidate boxes, and performing combination to obtain a fused description feature; performing type determination of the target candidate boxes based on a support vector machine (SVM) to obtain type attributes of the target candidate boxes and probabilities of belonging to corresponding types; and performing locating precision processing of the target candidate boxes to obtain an identification result of the airport target in the remote sensing image. By applying the method, the position and size of the airport can be quickly and accurately identified in the high-resolution remote sensing image; and the method is suitable for research on identification of the airport in the remote sensing image in various illumination conditions and various complex backgrounds.

Method and apparatus for displaying floating component

The invention discloses a method and an apparatus for displaying a floating component. The method comprises the following steps of: acquiring an application program window management control in a system; adding the application program of a custom component into the application program window management control, and setting the TYPE attribute parameters of the custom component to be the type of system prompt; when the custom component is triggered to display, displaying the custom component on the top layer of the interface of the system by means of a floating window. According to the method and the apparatus disclosed by the invention, when installation is carried out by a user and the custom component needs to be displayed, regardless of which other application programs are executed currently, the component can be always displayed on the topmost layer of all the programs by means of the floating window; in addition, the user can also move the position of the component, and can carry out corresponding interaction operations by clicking the component, for example, can start other programs, turn off music, control a network switch and the like, thus realizing information reminding and rapid processing, and increasing the operation efficiency of the user.

Method and device for supporting structured and unstructured big data fusion

The invention relates to a method for supporting structured and unstructured big data fusion. The method includes the steps: creating a multi-element big data fusion model supporting BLOB (binary large object) attribute values based on an attribute graph data model; generating N-element group data from received data by the multi-element big data fusion model supporting the BLOB attribute values; judging that the generated N-element group data are of a BLOB type and storing the BLOB type attribute values at a first preset position; fusing structured and unstructured big data at the first presetposition by controlling mapping between a handle and the data content of the corresponding BLOB type attribute value. The method provides a management model STRUNS for supporting structured and unstructured multi-element data fusion and an implementation system for the STRUNS. The method can be used for integrated management and uniform query of multi-element heterogeneous data including a text type, a Boolean type, a numeric type, a time type and the BLOB type, and a theoretical model and a practical system are provided for big data fusion management. The invention further relates to a device for supporting structured and unstructured big data fusion.

The invention discloses an urban street outline space form classification method and system, and the method comprises the steps: obtaining an urban building plane graph in a given range, carrying outthe division of the space in the plane graph, and obtaining a plurality of space units; setting a measuring point at the center of gravity of the space unit to obtain distance data of a space around the measuring point; calculating an urban space morphological characteristic index corresponding to each space unit according to the distance data of the space around the measurement point so as to form an urban space morphological characteristic index summary table; and forming an urban street outline space plane shape classification graph according to the urban space shape feature index summary table. According to the invention, the existing space is quantized and defined; more importantly, the spatial plane shape category is restored based on the quantitative index, the prediction spatial type attribute and the overall spatial feature are more accurate, the calculation cost is lower, and therefore a designer is helped to better understand the spatial attribute of the design object through the quantitative index at the initial design stage, and a pre-judgment measure is further provided.

Creating and monitoring alerts for geographical area

A geographical alert system creates an alert for a user-defined geographical area, detects a change to a feature stored in a map-related database, identifies whether the changed feature falls within the user-defined geographical area, and sends a notification to a user when the changed feature of the map-related database falls within the user-defined geographical area. To set up a geographical alert, an alert editor retrieves map data from a map-related database via an alert engine and displays the map data in a visual display to a user. The user then selects a geographical area that the system will automatically monitor for changes. The user may also specify a feature type, and an alert notification type for the alert. The alert engine then processes the user- specified geographical area into geographical area data and stores an alert and its corresponding geographical area data, feature type, and alert notification type in an alert database. When a change in the map-related database is detected, the alert engine obtains the geographic coordinate point data associated with the change and determines whether the geographical coordinate point data associated with the change falls within the geographical area of the stored alert in the alert database and if so, determines if the feature of the changed feature matches the feature of the stored alert. If the feature and geographical coordinate point data of the change corresponds to the feature and geographical area data of the stored alert, then the alert engine transmits an alert to the user using the alert notification type attributes of the stored alert.
