Systems and methods for correcting geometric distortions in videos and images
Abstract:
The geometric distortions of videos and images are corrected wherein a plurality of geometrically distorted frames are mapped with a plurality of original frames of the video content. Further, one or more features associated with the mapped frames are identified as insensitive to the one or more geometric distortions. One or more features of the mapped frames are further mapped with original frames based on a predefined similarity threshold and thereafter one or more geometric distortion parameters are determined. Furthermore, a frame level average distortion and a video level average distortion of each of the one or more geometric distortion parameters are determined, based on which the one or more geometric distortions of the video content are corrected.
