Abstract:
1. A method of reducing distortion in an image, the method comprising: receiving a captured image corresponding to a video sequence, the video sequence comprising one or more past images to the captured image and zero or more future images to the captured image; determining an orientation of a camera used to generate the captured image; computing a warp parameter based on the determined orientation of the camera; filtering the warp parameter in conjunction with either or both of past images and future images from the video sequence; computing an orientation indicator based, at least in part, on a difference between the determined orientation and a preferred orientation of the camera, wherein the orientation indicator indicates an orientation that, when applied to the camera, would orient the camera to more closely approximate the preferred orientation; applying, based on the filtered warp parameter, one or more warp techniques to the captured image to generate a distortion corrected image; and associating the orientation indicator with the distortion corrected image.
