Abstract
A video system processes video frames from a wide angle camera to dewarp the video frames in a manner that preserves conformity of an object of interest. A crop region of a video frame corresponding to the object of interest is determined. An input parameter to a dewarping function is generated based on the detected crop region. The dewarping function is applied to the crop region using the input parameter to generate a dewarped video frame and the dewarped video frame is outputted. The input parameter may be generated in a manner that causes the dewarped video frame to have higher conformity and lower distortion in the region around the object of interest than in a region distant from the object of interest.
