20110291925 | SYSTEM AND METHOD FOR OBJECT RECOGNITION AND TRACKING IN A VIDEO STREAM - Provided is a system and method for object detection and tracking in a video stream. Frames of the video stream are divided into regions of interest and a probability that the region contains at least a portion of an object to be tracked is calculated for each region of interest. The regions of interest in each frame are then classified based on the calculated probabilities. A region of interest (RI) frame is then constructed for each video frame that reports the classification of regions of interest in the video frame. Two or more RI frames are then compared in order to determine a motion of the object. Also provided is a system executing the presently described method, as well as a device including the system. The device may be for example, a portable computer, a mobile telephone, or an entertainment device. | 12-01-2011 |
20120092304 | SYSTEM AND METHOD FOR INPUTING USER COMMANDS TO A PROCESSOR - Provided is a system for inputting operation system (OS) commands to a data processing device. The system includes a video camera that captures images of a viewing space. A processor detects a predetermined object in the images using an object recognition algorithm not involving background information in an image. One or more image analysis parameters of the object are extracted from the images and one or more motion detection tests are applied. Each motion detection test has an associated OS command, and when a test succeeds, the OS command associated with the test is executed. By not relying on background information in an image, the described system may be used in devices that are moved in use, such as a palm plot, personal digital assistant (PDA), a mobile telephone, a digital camera, and a mobile game machine. | 04-19-2012 |

20140157210 | Gesture Based Interface System and Method - A user interface apparatus for controlling any kind of a device. Images obtained by an image sensor in a region adjacent to the device are input to a gesture recognition system which analyzes images obtained by the image sensor to identify one or more gestures. A message decision maker generates a message based upon an identified gesture and a recognition mode of the gesture recognition system. The recognition mode is changed under one or more various conditions. | 06-05-2014 |
20140168062 | SYSTEMS AND METHODS FOR TRIGGERING ACTIONS BASED ON TOUCH-FREE GESTURE DETECTION - Systems, methods and non-transitory computer-readable media for triggering actions based on touch-free gesture detection are disclosed. The disclosed systems may include at least one processor. A processor may be configured to receive image information from an image sensor, detect in the image information a gesture performed by a user, detect a location of the gesture in the image information, access information associated with at least one control boundary, the control boundary relating to a physical dimension of a device in a field of view of the user, or a physical dimension of a body of the user as perceived by the image sensor, and cause an action associated with the detected gesture, the detected gesture location, and a relationship between the detected gesture location and the control boundary. | 06-19-2014 |

20140361988 | Touch Free Interface for Augmented Reality Systems - A method and system for augmented reality. Images of a real world scene are obtained from one or more from one or more image sensors. An orientation and/or location of the image sensors is obtained from one or more state sensors. A real world object at which a predefined pointing object is performing a predefined gesture in the images of the real world scene is identified and data associated with the identified object is displayed on a viewing device. The invention also provides a computer program comprising computer program code means for performing all the steps of the method of the invention when said program is run on a computer. | 12-11-2014 |
20140375547 | TOUCH FREE USER INTERFACE - The presently disclosed subject matter includes a method of recognizing an aimed point on a plane. Images captured by one or more image sensor are processed for obtaining data obtaining data indicative of location of at least one pointing element in the viewing space and data indicative of at least one predefined user's body part in the viewing space; using the obtained data an aimed point on the plane is identified. In case it is determined that a predefined condition is met a predefined command and/or message is executed. | 12-25-2014 |
