1. A system comprising: a processor configured to execute computer-readable instructions to, determine an estimated shear due to a rolling shutter in a plurality of regions of a current frame of an image; and determine an estimated depth of an object in the image based on the estimated shear, the processor further configured to execute the computer-readable instructions to, obtain a previous frame of the image, obtain the current frame of the image, determine motion vector data for the plurality of regions, respectively, the motion vector data representing motion between corresponding regions in the previous frame and the current frame, determine local motion vector data and global motion vector data among the motion vector data for the plurality of regions, and segment the global motion vector data into segments, wherein each scgment is associated with a different motion, the estimated shear being based on the segmented global motion vector data.
