Stabilizing image sequences based on camera rotation and focal length parameters
Abstract:
The present disclosure describes systems and processes for image sequence stabilization. According to particular embodiments, a sequence of images is obtained using a camera which captures the sequence of images along a camera translation. Each image contains at least a portion of overlapping subject matter. A plurality of keypoints is identified on a first image of the sequence of images. Each keypoint from the first image are kept track of to a second image. Using a predetermined algorithm, a camera rotation value and a focal length value are calculated from two randomly sampled keypoints on the first image and two corresponding keypoints on the second image. An optimal camera rotation and focal length pair corresponding to an optimal transformation for producing an image warp for image sequence stabilization is determined. The image warp for image sequence stabilization is constructed using the optimal camera and focal length pair.
