SYSTEM AND METHOD FOR EFFECTIVE SECTION DETECTING OF HAND GESTURE
First Claim
Patent Images
1. A method for detecting an effective section of a gesture, the method comprising:
- acquiring, by a controller, an image that includes the gesture and a background;
extracting, by the controller, pose information and motion information included in the gesture as features;
determining, by the controller, whether a pose has been recognized based on the pose information;
in response to determining that a pose has been recognized, detecting, by the controller, the effective section of the gesture based on a start point and an end point of the pose; and
in response to detecting the effective section of the gesture, recognizing, by the controller, the gesture based on the motion information.

Abstract
A system is provided for detecting an effective section of a gesture by recognizing the gesture, pose information and motion information included in the gesture from an acquired image. In addition, a controller determines whether a pose has been recognized based on the pose information and when the pose has been recognized, an effective section is detected based on a start point and an end point of the pose. Further, when the effective section for the pose is detected, the gesture is recognized based on the motion information.

9. A system that detects an effective section of a hand gesture, the system comprising:
a controller configured to; acquire an image having a background and the gesture that includes pose information and motion information; detect the pose information and the motion information from the gesture; extract the pose information by determining whether information corresponding to the motion information is in stored feature information; detect a start point of the pose information, in response to detecting the pose information; detect an end point of the pose information, in response to detecting the pose information; and detect the effective section for the pose based on the start point and the end point; and recognize a gesture by determining whether the extracted motion information is included in the stored feature information, in response to detecting the effective section. - View Dependent Claims (10, 11, 12)

13. A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:
-
program instructions that acquire an image having a background and the gesture that includes pose information and motion information; program instructions that detect the pose information and the motion information from the gesture; program instructions that extract the pose information by determining whether information corresponding to the motion information is in stored feature information; program instructions that detect a start point of the pose information, in response to detecting the pose information; program instructions that detect an end point of the pose information, in response to detecting the pose information; and program instructions that detect the effective section for the pose based on the start point and the end point; and program instructions that recognize a gesture by determining whether the extracted motion information is included in the stored feature information, in response to detecting the effective section. - View Dependent Claims (14)
