Abstract: A coal flow identification method based on a background subtraction algorithm, including: S1: simultaneously capturing images of a coal layer at a coal unloading end of a scraper conveyor using a plurality of cameras mounted on a reversed loader in parallel; S2: determining an optimal sequence image of simultaneously captured three sequence images, and delimiting a region of interest; S3: extracting a motion region outline in the image; S4: performing line adding repair on the motion region outline, and padding the repaired motion region outline; S5: calculating a number of pixels in a motion region, and calculating an area of the motion region according to a scale; and S6: calculating a coal flow volume.

Abstract: The present invention relates to the technical field of mining belt conveyors, and particularly to a system for visually identifying and positioning a tearing fault of a conveyer belt of a mining belt conveyor.

Abstract: A video transcoding method and apparatus, a device, a storage medium, and a video-on-demand system. The video transcoding method includes: determining a target video transcoding mode based on a video distribution scenario of a video to be transcoded; and performing a transcoding operation on the video to be transcoded based on the target video transcoding mode to obtain a transcoded video file corresponding to the video to be transcoded, and store the transcoded video file, so as to generate a target playback video for playback based on the transcoded video file when a video playback request is detected.

Abstract: A pharmaceutical composition comprising a small molecule EGFR inhibitor and a preparation method therefor, the composition comprising N-(5-((4-(1-cyclopropyl-1H-indol-3-yl)pyrimidin-2-yl)amino)-2-((2-(dimethylamino)ethyl)(methyl)amino)-4-methoxyphenyl)acrylamide, an isomer, solvate, hydrate, or pharmaceutically acceptable salt thereof, or a combination thereof that acts as an active ingredient, and at least one pharmaceutically acceptable excipient.

Abstract: An electronic transaction processing method, including: receiving a self-verification request, sent by a payee terminal, for an order transaction; and determining whether transaction verification information carried in the self-verification request matches verification information of the order transaction, wherein the verification information of the order transaction is sent to an associated payer account when the order transaction is successful; and if both match, not carrying out reversal processing.
