Abstract: Disclosed herein are a method for tracking object in video in real time in consideration of both color and shape and an apparatus for the same. The apparatus may generate at least one of a correlation filter model and a color probability density model based on an input image, determine an initial position and an initial size of a target to be tracked based on a correlation filter response value calculated by applying the correlation filter model to the input image, calculate a joint probability based on the correlation filter response value and a color object probability that is calculated based on the color probability density model, and update an object model corresponding to the target to be tracked based on a final position and a final size of the target to be tracked, which are determined by applying the joint probability to the initial position and the initial size.

Abstract: A method and apparatus of generating a path for autonomous navigation of a mobile computing apparatus is provided. The mobile computing apparatus includes one or more processors configured to map a set global path, which connects a current position of the mobile computing apparatus with a future destination of the mobile computing apparatus based on a topology map, to a real-time generated occupancy grid map that represents, based on sensor data of a surrounding environment of the mobile computing apparatus, an un-drivable area and a drivable area in the surrounding environment, and generate a local path, for a traveling of the mobile computing apparatus, connecting the current position with a sub-waypoint that corresponds to the drivable area in response to a next waypoint, to which the mobile computing apparatus is set to travel based on the global path, being determined to correspond to the un-drivable area.
