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 recgonized, 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 guesture, recognizing, by the controller, the gesture based on the motion information,wherein the detecting of the effective section of the gesture includes;
detecting, by the controller, the start point of the pose;
detecting, by the controller, the end point of the pose;
determining, by the controller, whether the section from the start point to the end point continues for a predetermined time or more; and
in respond to determining that the section continues for the predetermined time or more, determining, by the controller, the section between the start point to the end point as the effective section.

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.

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 recgonized, 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 guesture, recognizing, by the controller, the gesture based on the motion information, wherein the detecting of the effective section of the gesture includes; detecting, by the controller, the start point of the pose; detecting, by the controller, the end point of the pose; determining, by the controller, whether the section from the start point to the end point continues for a predetermined time or more; and in respond to determining that the section continues for the predetermined time or more, determining, by the controller, the section between the start point to the end point as the effective section. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. 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, wherein for the detection of the effective section of the gesture, the controller is further configures to; detect the start point of the pose; detect the end point of the pose; determine whether the section from the start point to the end point continues for a predetermined time or more; and in response to determining that the section continues for the predetermined time or more, determine the section between the start point to the end point as the effective section. - View Dependent Claims (9, 10, 11)

12. 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, wherein the detection of the effective section of the gesture further includes; program instructions that detect the start point of the pose; program instructions that detect the end point of the pose; program instructions that determine whether the section from the start point to the end point continues for the a predetermined time or more; and program instructions that determine the section between the start point to the end point as the effective section in response to determine that the section continues for the predetermined time or more. - View Dependent Claims (13)
