Abstract: An example apparatus for detecting objects in video frames includes a receiver to receive a plurality of video frames from a video camera. The apparatus also includes a first still image object detector to receive a first frame of the plurality of video frames and calculate localization information and confidence information for each potential object patch in the first frame. The apparatus further includes a second still image object detector to receive an adjacent frame of the plurality of video frames adjacent to the first frame and calculate localization information and confidence information for each potential object patch in the adjacent frame. The apparatus includes a similarity detector trained to detect paired patches between the first frame and the adjacent frame based on a comparison of the detected potential object patches.

Abstract: An ethylene copolymer and a method for preparing same, and a composition, crosslinked polymer, and tire containing said ethylene copolymer are provided. The ethylene copolymer contains an ethylene structural unit derived from ethylene and a conjugated diene structural unit derived from a conjugated diene. Taking the total amount of said ethylene copolymer as the reference, the content of said conjugated diene structural unit is 25-45 mol %. The conjugated diene is formed by 1,2-polymerization and the content of 1,2-polymeric vinyl structural units having side chain double bonds is 20-40 mol %. Taking the total number of conjugated diene structural units in the ethylene copolymer as the reference. The total amount of said 1,2-polymeric structural units is 95 mol % or more, and the ethylene copolymer has a weight average molecular weight of 20,000 to 300,000.
