Abstract: A system and method of video processing are disclosed. In a particular implementation, a device includes a processor configured to generate index data for video content. The index data includes a summary frame and metadata. The summary frame is associated with a portion of the video content and illustrates multiple representations of an object included in the portion of the video content. The metadata includes marker data that indicates a playback position of the video content. The playback position is associated with the summary frame. The device also includes a memory configured to store the index data.

Abstract: Aspects for sensing total current of distributed load circuits independently of a spatial profile of the total current using distributed voltage averaging are disclosed. In one aspect, a current sense circuit is configured to sense total current of a distributed load circuit independently of where current is distributed. The current sense circuit includes distributed voltage averaging circuits configured to determine average voltages of the distributed load circuit based on voltages sensed at multiple resistive paths corresponding to a distribution network configured to provide voltage to the distributed load circuit. An amplifier includes an output node having an output voltage that is proportional to total current flowing in the distributed load circuit. The current sense circuit allows for sensing total current independent of where the current flows, providing more accurate current sensing compared to sensing current in one area of the distributed load circuit.

Abstract: A system and method of video processing are disclosed. In a particular implementation, a device includes a frame buffer configured to receive a video frame sequence and to store the video frame sequence and a frame index for each frame of the video frame sequence. The device also includes a processor configured to compress a summary frame into an encoded file representative of the summary frame. The summary frame includes a first representation of an object at a first position in a first video frame associated with a first frame index of the video frame sequence. The summary frame further includes a second representation of an object at a second position in a second video frame associated with a second frame index associated with the video frame sequence. The device also includes a transmitter configured to output a notification signal associated with the summary frame.

Abstract: A method of generating a temporal saliency map is disclosed. In a particular embodiment, the method includes receiving an object bounding box from an object tracker. The method includes cropping a video frame based at least in part on the object bounding box to generate a cropped image. The method further includes performing spatial dual segmentation on the cropped image to generate an initial mask and performing temporal mask refinement on the initial mask to generate a refined mask. The method also includes generating a temporal saliency map based at least in part on the refined mask.

Abstract: A method includes receiving a user input (e.g., a one-touch user input), performing segmentation to generate multiple candidate regions of interest (ROIs) in response to the user input, and performing ROI fusion to generate a final ROI (e.g., for a computer vision application). In some cases, the segmentation may include motion-based segmentation, color-based segmentation, or a combination thereof. Further, in some cases, the ROI fusion may include intraframe (or spatial) ROI fusion, temporal ROI fusion, or a combination thereof.
