Abstract: A smart cache implementation for image warping is provided by dividing an output image into a plurality of blocks corresponding to initial coordinates in the output image; dividing an input image into at least a first and second regions of pixels, where the first region overlaps the second region; generating an unsorted remap vector of the plurality of blocks for image warping the input image; identifying a first and second subsets of blocks from the plurality of blocks that can be reconstructed using the first and second regions respectively; generating a region-based sorting, a line-based sorting of the region-based sorting, a column-based sorting of the line-based sorting based on the initial x-coordinates of the blocks in the unsorted remap vector, and a sorted remap vector by sorting the column-based sorting based on initial y-coordinates of the blocks in the unsorted remap vector.

Abstract: The disclosed computer-implemented method for updating locked states may include (i) identifying a computing system and a mobile device that are both operated by a user, (ii) using a signal strength between the computing system and the mobile device to calculate a physical distance between the mobile device and the computing system that correlates to a proximity of the user to the computing system, (iii) calibrating, based on input from a sensor that indicates an activity of the user, a parameter for calculating the physical distance, (iv) using the signal strength and the parameter to recalculate the physical distance, and (v) updating, based at least in part on the recalculated physical distance, a locked state of the computing system in response to a change in the proximity of the user to the computing system. Various other methods, systems, and computer-readable media are also disclosed.
