  • Publication number: 20150067589
    Abstract: An operation processing method and an operation processing device applied in an electronic apparatus include a display unit in which a first interactive interface having a first size is displayed. The method includes displaying a second interactive interface having a second size which is different from the first size and having a mapping relation with the first interactive interface in the display unit, detecting a first action executed by the user in the second interactive interface; and executing a first operation in the first interactive interface according to the first action. Thus, the first interactive interface can be mapped into the second interactive interface and the first operation that the user expects to execute in the first interactive interface can be implemented by the first action executed in the second interactive interface, so that the user can conveniently operate the electronic apparatus.

  • Publication number: 20140324888
    Abstract: A method, apparatus and computer program product are provided to permit improve gesture recognition based on fusion of different types of sensor signals. In the context of a method, a series of image frames and a sequence of radar signals are received. The method determines an evaluation score for the series of image frames that is indicative of a gesture. This determination of the evaluation score may be based on the motion blocks in an image area and the shift of the motion blocks between image frames. The method also determines an evaluation score for the sequence of radar signals that is indicative of the gesture. This determination of the evaluation score may be based upon the sign distribution in the sequence and the intensity distribution in the sequence. The method weighs each of the evaluation scores and fuses the evaluation scores, following the weighting, to identify the gesture.

  • Publication number: 20140129676
    Abstract: An approach is provided for enhancing a communication session. The approach involves receiving a request for communicating at least substantially live video data between a device and one or more other devices. The approach also involves determining capability information, resource availability information, or a combination thereof of the device, the one or more other devices, or a combination thereof. The approach further involves processing and/or facilitating a processing of the capability information, the resource availability information, or a combination thereof to cause, at least in part, an extraction of multimodal information from the at least substantially live video data. The approach additionally involves causing, at least in part, an exchange of the multimodal information in place of at least a portion of the at least substantially live video data in response to the request.

  • Publication number: 20130251274
    Abstract: An example apparatus is caused to receive a video sequence of a plurality of frames, and perform a number of operations as each of at least some of the frames is received but before all of the frames are received. The apparatus is caused to calculate a score for the frame, and compare the score for the frame to a predefined threshold. The apparatus is caused to cause output of the frame as a key frame in an instance in which the frame is received within a specified period of time and the score for the frame is above the predefined threshold. Otherwise, in an instance in which none of the scores for frames received within the specified period of time is above the predefined threshold, the apparatus is caused to cause output of one of the frames received within the specified period of time as a key frame.

  • Publication number: 20130182767
    Abstract: An example apparatus is caused to receive a video sequence of a plurality of frames, and activate one of a plurality of available decoding processes based on a comparison of a size of the frames to a predefined threshold. The apparatus is also caused to select some but not all of the frames of the video sequence as potential key frames of the video sequence. The selected frames are located at or close to predefined positions along a length of the video sequence. The apparatus is also caused to decode the potential key frames according to the activated decoding process, and cause output of at least some of the potential key frames as key frames of the video sequence. The apparatus may be caused to discard from the potential key frames, one or more plain frames and/or a frame identified as being similar to other potential key frames.

  • Patent number: 8180158
    Abstract: An image processing device capable of high-speed detection of a specific shape in an image. In the image processing device, a candidate position calculation section (106) obtains a first candidate position of the center point of a first circle in contact at three points with three sides contained in the shape of an object to be detected. An angle calculation section (106) obtains an angle formed by a normal line drawn from each of the three sides to the first candidate position and a standard line oriented in a specific direction and passing a point at which the normal line and each of the three sides cross. A relative relationship calculation section (106) obtains a relationship of the angle relative to the first candidate position. A recognition section (108) recognizes the shape contained in the given image based on the relative relationship of the angle and a relative relationship of a shape stored in advance.
