摘要： In one embodiment, an image processor is configured to obtain a plurality of phase images for each of first and second depth frames. For each of a plurality of pixels of a given one of the phase images of the first depth frame, the image processor determines an amount of movement of a point of an imaged scene between the pixel of the given phase image and a pixel of a corresponding phase image of the second depth frame, and adjusts pixel values of respective other phase images of the first depth frame based on the determined amount of movement. A motion compensated first depth image is generated utilizing the given phase image and the adjusted other phase images of the first depth frame. Movement of a point of the imaged scene is determined, for example, between pixels of respective n-th phase images of the first and second depth frames.

摘要： An image processing system comprises an image processor configured to determine velocity of a hand in a plurality of images, and to selectively enable dynamic gesture recognition for at least one image responsive to the determined velocity. By way of example, the image processor illustratively includes a dynamic gesture preprocessing detector and a dynamic gesture recognizer, with the dynamic gesture preprocessing detector being configured to determine the velocity of the hand for a current frame and to compare the determined velocity to a specified velocity threshold. If the determined velocity is greater than or equal to the velocity threshold, the dynamic gesture recognizer operates on the current frame, and otherwise the dynamic gesture recognizer is bypassed for the current frame. The dynamic gesture recognizer when enabled is configured to generate similarity measures for respective ones of a plurality of gestures of a gesture vocabulary for the current frame.

摘要： An image processing system comprises an image processor configured to establish a main processing thread and a parallel processing thread for respective portions of a multithreaded gesture recognition process. The parallel processing thread is configured to utilize buffer circuitry of the image processor, such as one or more double buffers of the buffer circuitry, so as to permit the parallel processing thread to run asynchronously to the main processing thread. The parallel processing thread implements one of noise estimation, background estimation and static hand pose recognition for the multithreaded gesture recognition process. Additional processing threads may be established to run in parallel with the main processing thread. For example, the image processor may establish a first parallel processing thread implementing the noise estimation, a second parallel processing thread implementing the background estimation, and a third parallel processing thread implementing the static hand pose recognition.
