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 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.
