Abstract: A fetal Doppler (10) and a detection method, which relate to the technical field of medical devices. The fetal Doppler (10) comprises a housing (1, a fetal detection unit (20) and a maternal parameter detection unit (30), wherein the fetal detection unit (20) and the maternal parameter detection unit (30) are respectively used for collecting fetal physiological data and maternal physiological data; a controller (7) is arranged in an internal cavity of the housing (1); and the controller (7) is used for analyzing the collected fetal physiological data and maternal physiological data, so as to obtain a fetal heart rate and a maternal parameter. The same fetal Doppler (10) is used, such that the instrument cost is reduced; and maternal and fetal parameters can be acquired at the same time by directly using the same fetal Doppler (10), such that an instrument structure is simplified, and the detection efficiency of the maternal and fetal parameters is improved.

Abstract: A method for generating a video cover is performed by a computer device and includes acquiring a video title and a candidate video cover of a target video; determining highlighted characters of the video title; determining typesetting parameters of the highlighted characters based on the highlighted characters and a cover parameter of the candidate video cover; and generating a target video cover of the target video by rendering the highlighted characters to the candidate video cover based on the typesetting parameters.

Abstract: A scene-based beam generation method for ground-to-air coverage based on convex polygon subdivision is provided and includes: obtaining a collection of base station positions by using a method of universal transverse mercator projection; constructing a three-dimensional (3D) low altitude signal coverage area; performing convex polygon subdivision on the area to be covered; and generating a beam configuration of each base station. The method realizes generation of beam configurations of base stations in the 3D low altitude signal coverage area, overcomes a problem that the existing 17 kind of scene-based beams cannot realize the coverage of 3D area, overcomes a problem of mismatch between network state information and beam configuration caused by dynamic adjustment of beam configurations. The beam configurations generated by the method does not need to obtain the number of users in real time to adjust the beam, and has a good coverage ability.

Abstract: Embodiments of this application provide an image processing method and apparatus, and a computer-readable storage medium. The image processing method includes obtaining an image and size information corresponding to the image; determining a target center point of the image according to position information of facial feature information in the image; determining cropped size information according to an aspect ratio relationship between the size information and target size information, the target size information being size information of a thumbnail that is to be generated and corresponds to the image; cropping the image based on the target center point and the cropped size information to obtain a target image, an aspect ratio of the target image being same as an aspect ratio of the target size information; and scaling the target image according to the target size information, to generate the thumbnail with the target size information.

Abstract: An image processing method includes: performing target object detection on an initial image to obtain an object detection result, and performing image saliency detection on the initial image to obtain a saliency detection result; cropping the initial image based on the object detection result and the saliency detection result to obtain a corresponding cropped image; acquiring an image template for indicating an image style, and acquiring layer information corresponding to the image template; and adding the layer information to the cropped image based on the image template to obtain a target image corresponding to the image style indicated by the image template.

Abstract: A method for enhancing network coverage based on adaptive generation of resource cell. A traditional cell in a network is taken as an initial state of the network. A correlation matrix in a current network state is generated. Whether |?i,jt??i,jt-1|/?i,jt-1>? is determined. Each access point is divided into a plurality of resource cells. A CU-DU network mapping table is generated. A middlehaul link of each of the plurality of resource cells is constructed according to the CU-DU network mapping table.

Abstract: A method and system for identifying and processing text operation instruction, and a server are provided. The method includes a communication terminal performing: presenting a communication session window between a user and a network transaction system; receiving text information input by the user in the communication session window, and performing text semantic analysis on the text information to determine an operation type and an operation instruction field; sending the determined operation type and operation instruction field to the network transaction system; and receiving response information returned by the network transaction system, and outputting the response information to the communication session window.

Abstract: The present disclosure provides a method for searching information in electronic commerce platform including: organizing information in the electronic commerce platform in advance according to categories, products and commodities; wherein each product includes a product name and attribute information including attribute names and all possible attribute values corresponding to each attribute name; obtaining one search keyword, matching the search keyword with attribute values of each product, respectively, and using successfully matched products to form a first search result set; matching the search keyword with a product name of each product, respectively, and using successfully matched products to form a second search result set; displaying each search result. A displaying order of each search result in the first search result set takes precedent over a displaying order of each search result in the second search result set.

Abstract: A method and system for displaying commodity search results are provided. A commodity keyword input by a user may be received. A search may be executed based on the commodity keyword input by the user. A commodity list searched out may be obtained. Key attributes of all of the commodities in the commodity list may be extracted. Commodities with the same key attributes may be identified. The commodities with the same key attributes may be aggregated into one Standard Product Unit (SPU) product. The SPU product, which has aggregated the commodities with the same key attributes, may be displayed.

Abstract: Disclosed are a method and apparatus for classifying commodities on an e-commerce platform. The method includes: setting a classification for each commodity according to a property of the commodity; setting one or more attributes for each classification according to the category; setting at least one attribute value for each attribute according to the attribute; generating a category map according to a category map generation sequence, and a mapping relationship between the classification and attribute value, and categories and sub-categories in the category map, and using the category map as a commodity classification result. According to the embodiments of the present disclosure, by setting a classification-attribute system on the background of an e-commerce website, a category map is adaptively constructed; in this way, the category map is adaptively generated according to the classification and attribute value.
