Abstract
An apparatus is configured to perform a method of parallax tolerant video stitching. The method includes determining a plurality of video sequences to be stitched together; performing a spatial-temporal localized warping computation process on the video sequences to determine a plurality of target warping maps; warping a plurality of frames among the video sequences into a plurality of target virtual frames using the target warping maps; performing a spatial-temporal content-based seam finding process on the target virtual frames to determine a plurality of target seam maps; and stitching the video sequences together using the target seam maps.
