摘要： A method of removing a motion vector from a group of motion vectors used in an encoding process includes providing a list of motion vectors, selecting an initial motion vector from the list of motion vectors, and providing an intermediate motion vector using a motion vector refinement process. The motion vector refinement process uses, in part, the initial motion vector. The method also includes forming a region defined by one or more parameters associated with the initial motion vector and one or more parameters associated with the intermediate motion vector, selecting an additional motion vector from the list of motion vectors, determining that the additional motion vector points into the region, and modifying a state of the additional motion vector.

A first embodiment of the present invention provides an apparatus and a method for a Reduced-Algorithmic-Delay Media Stream Unit Conversion module which is a light weight Simple Pass-Through operation. A second embodiment of the present invention provides an apparatus and a method for a Reduced-Algorithmic-Delay Video Rate Conversion. An alternative embodiment provides an apparatus and a method for a Smart Pass-Through Operation which involves switching between the Simple Pass-Through and the Rate Converter. The methods and apparatuses provided by the first and second embodiment can be used as a stand alone system, or as part of the module of the alternative embodiment.

摘要： Methods and systems for discrete control of user interface elements such as graphical widgets are described. A first plurality of video frames are captured and processed to recognize hand gestures therein. A dragging mode is activated in response to a dragging mode activation hand gesture in the first plurality of frames. A second plurality of video frames are captured and processed to allow recognition of hand gestures therein. Dragging, an element of a user interface control, in response to recognition of a discrete control hand gesture in the second plurality of frames. The discrete control of a user interface control using mid-air hand gestures allows precise setting of system parameters associated with the user interface control.

摘要： Devices and methods for providing feedback for a control display (CD) gain of a slider control on a gesture-controlled device are described. The method includes detecting a speed of a dynamic dragging gesture, determining the CD gain for the slider control based on the speed, and generating an auditory feedback or a visual feedback for the CD gain. A gesture-controlled device, which carries out the method, may have an image-capturing device, a processor, and a memory coupled to the processor, the memory storing machine-executable instructions for carrying out the method. Advantageously, providing feedback for CD gain of a slider control facilitates accurate adjustment of a system parameter associated with the slider control. The devices and methods may be used in industrial applications, vehicle control among other applications.
