Although the distortion correction of fisheye images has been extensively studied, the correction of fisheye videos is still an elusive challenge.
For different frames of the fisheye video, the existing image correction methods ignore the correlation of sequences, resulting in temporal jitter in the corrected video.
... propose a temporal weighting scheme to get a plausible global optical flow, which mitigates the jitter effect by progressively reducing the weight of frames.
... observe that the inter-frame optical flow of the video is facilitated to perceive the local spatial deformation of the fisheye video.
... a temporal deformation aggregator is designed to reconstruct the deformation correlation between frames and provide a reliable global feature.
... method achieves an end-to-end correction and demonstrates superiority in correction quality and stability compared with the SOTA correction methods.
