Abstract: The application provides an apparatus and a method for procedural video assessment. The apparatus includes: interface circuitry; and processor circuitry coupled to the interface circuitry and configured to: perform an action segmentation process for a procedural video received via the interface circuitry to obtain a plurality of action features associated with the procedure video; transform the plurality of action features into a plurality of action-procedure features based on an action-procedure relationship learning module for discovering a relationship between the plurality of action features and a plurality of scoring oriented procedures associated with the procedure video; and perform a procedure classification process to infer the plurality of scoring oriented procedures from the plurality of action-procedure features.

Abstract: Disclosed herein is a gesture recognition device that includes an input interface configured to receive a sequence of images, each image showing a body part with which a gesture is performed from a viewpoint of a camera. The gesture recognition device also generates a sequence of motion-compensated images from the sequence comprising generating a motion-compensated image for an image of the sequence by compensating the movement of the camera viewpoint from a reference camera viewpoint to the viewpoint from which the image shows the body part based on the image and a motion-compensated image of the sequence generated for a preceding image of the sequence which precedes the image in the sequence and estimate the gesture from the sequence of motion-compensated images.

Abstract: The disclosure provides techniques for map optimization for a localization and mapping system. The map optimization method includes segmenting, based on a preset segmentation condition, a trajectory tracked by the localization and mapping system to obtain a plurality of segments of the trajectory, each segment being partitioned into a head part, an interior part and a tail part; performing a global optimization process based on frames in the head and tail parts of each segment to obtain optimized mapping results for the frames in the head and tail parts of the segment; estimating optimized mapping results for frames in the interior part of each segment based on the optimized mapping results for the frames in the head and tail parts of the segment; and updating a map built by the localization and mapping system according to the optimized mapping results for the frames in each segment.

Abstract: The disclosure provides techniques for registering a camera into a map via a robot. A method for registering a camera into a map may include: collecting an observation of a calibration marker from an image captured by the camera, the calibration maker being attached to a robot capable of moving in a view of the camera; calculating, for the observation of the calibration marker, a transform T (camera, marker) between a camera frame of the camera and a marker frame of the calibration marker; obtaining, for the observation of the calibration marker, a transform T (world, robot) between a world frame of the map and a robot frame of the robot; and performing, when more than a predetermined number of observations of the calibration marker are collected during movement of the robot, a calibration process to calculate a transform T(world, camera) between the world frame and the camera frame based on the transform T (camera, marker) and the transform T(world, robot) for each observation of the calibration marker.
