In other aspects, multiangled extravascular images are captured and analyzed in order to identify the size and orientation of branch vessels.

Abstract: A method of labeling video to provide authentication acquires an instruction to apply timestamp labeling. Each recorded video is labeled with a timestamp based on the instruction.

By comparing the first mark information and the second mark information, a video under investigation is found to be undistorted and authentic when the first mark information is the same as the second mark information. The video under investigation is found to be non-authentic when the first mark information is different from the second mark information. A terminal device and a computer readable storage medium applying the method are also disclosed.

Abstract: Systems and methods for generating object segmentations across videos are provided. An example system can enable an annotator to identify objects within a first image frame of a video sequence by clicking anywhere within the object. The system processes the first image frame and a second, subsequent, image frame to assign each pixel of the second image frame to one of the objects identified in the first image frame or the background. The system refines the resulting object masks for the second image frame using a recurrent attention module based on contextual features extracted from the second image frame. The system receives additional user input for the second image frame and uses the input, in combination with the object masks for the second image frame, to determine object masks for a third, subsequent, image frame in the video sequence. The process is repeated for each image in the video sequence.
