Abstract: Provided is a method for processing video coding. The method includes: according to domain image blocks of a target image block in a video frame, determining whether the target image block belongs to a candidate caption region; in response to determining that the target image block belongs to the candidate caption region, generating a pixel histogram of the target image block; according to the pixel histogram of the target image block, determining a region type to which the target image block belongs, where the region type is a caption region or a non-caption region; and according to the region type to which the target image block belongs, determining a target coding mode for the target image block.

Abstract: A control handle for operating an interventional assembly includes: two support bodies arranged sequentially in the axial direction and including a first support body and a second support body located at a proximal end of the first support body, the two support bodies being slidably engaged with each other in the axial direction; a plurality of mounting seats installed on the corresponding support bodies fixedly or movably, a mounting seat(s) on one support body is configured to connect the bending component, and a mounting seat(s) on the other support body is configured to connect the delivery tube; and a plurality of driving members movably installed on the corresponding support bodies, which are engaged with and configured to drive the corresponding mounting seats on the support bodies.

Abstract: The present disclosure provides use of a Chaetomium globosum strain in controlling Fusarium crown rot (FCR) of wheat. The C. globosum strain under the deposit designation of 12XP1-2-3 is deposited at China General Microbiological Culture Collection Center (CGMCC) on Jan. 23, 2019 with an accession number of CGMCC No. 17183. Field experiments conclude that coating of wheat seeds with Chaetomium globosum strain 12XP1-2-3 can reduce diseased stem rate, disease rating, and disease index by 19.0%-41.3%, 43.7%, and 4.7%-45.4%, respectively.

The automatic minor repair operation apparatus system includes: a workover machine, a pipe column conveying and discharging device, an elevator for a workover operation, a manipulator for a workover operation, an integrated automatic wellhead operation apparatus, and a power slip for an oil field workover operation.

Abstract: A set of rough prediction modes including a MPM subset is determined for a code block during image encoding. A first prediction mode having a mode cost less than a first threshold is selected from the set of rough prediction modes, and a second prediction mode having a mode cost less than a second threshold is selected from the MPM subset. A candidate mode subset is determined based on mode types of prediction modes contained in the set of rough prediction modes and a ranking result of mode costs of the prediction modes, when the mode cost of the first prediction mode is different from the mode cost of the second prediction mode. A target prediction mode is determined for the code block from the candidate mode subset. The code block is encoded with the target prediction mode.

Abstract: An method for determining a video coding test sequence, an electronic device, and a computer readable storage medium are provided. The method includes: determining a candidate video set including multiple candidate videos corresponding to a target service requirement; classifying the candidate videos by content categories to obtain a target distribution of content categories; clustering the candidate videos by values of a preset coding complexity to obtain multiple video classes; selecting from each of the video classes respectively a target class-representative video such that an actual distribution of content categories is consistent with the target distribution of content categories; and constructing a target video coding test sequence based on the target class-representative videos.
