Abstract: A method includes constructing map information by obtaining information of environment of a target mowing area, generating a 3-D space path along which the robot having mowing equipment mounted thereon is to move in the target mowing area based on the constructed map information, driving the robot so that the robot travels along the 3-D space path in response to an instruction for executing a mowing mode, extracting a ground area and an obstacle for robot driving by extracting information of a 3-D space when traveling along the 3-D space path, adaptively controlling the driving and mowing mode of the robot based on the extracted ground area and obstacle, and terminating the mowing mode when detecting a completion of the mowing for the target mowing area during the mowing mode.

Abstract: An image recognizing apparatus includes a sample image acquiring unit configured to acquire a sample image having one or more target objects therein from a camera; and a reference range setting unit configured to calculate image locations and image heights for the respective target objects from the sample image and set a reference range of the image heights depending on the image positions. Further, the image recognizing apparatus includes a selection unit configured to determine whether a candidate area of each target object in the sample image acquired by the camera falls within the reference range to select an effective candidate area.

Abstract: A method for human activity prediction from streaming videos includes extracting space-time local features from video streams containing video information related to human activities; and clustering the extracted space-time local features into multiple visual words based on the appearance of the features. Further, the method for the human activity prediction includes computing an activity likelihood value by modeling each activity as an integral histogram of the visual words; and predicting the human activity based on the computed activity likelihood value.
