Systems and methods for correcting geometric distortions in videos and images

摘要

The technique relates to a system and method for correcting geometric distortions in videos and images. To correct the one or more geometric distortions in videos, the frames of the original and distorted video are mapped at the beginning and then the features associated with the mapped frames which are insensitive to geometric distortions are identified. In case of correcting geometric distortions in images, frame mapping is not required and thus the process starts from identifying the features insensitive to geometric distortions in the original image and distorted image. Then, the geometric distortion parameters are identified from the mapped features. After that, a frame level and video level average distortion of the geometric distortion parameters are determined. Finally, the geometric distortions are corrected based on the frame level and video level average distortion value. REF FIG: 1
