Bitstream-Corrupted JPEG Images are Restorable: Two-stage Compensation and Alignment Framework for Image Restoration. (arXiv:2304.06976v1 [eess.IV])

In this paper, we study a real-world JPEG image restoration problem with bit
errors on the encrypted bitstream. The bit errors bring unpredictable color
casts and block shifts on decoded image contents, which cannot be resolved by
existing image restoration methods mainly relying on pre-defined degradation
models in the pixel domain. To address these challenges, we propose a robust
JPEG decoder, followed by a two-stage compensation and alignment framework to
restore bitstream-corrupted JPEG images. Specifically, the robust JPEG decoder
adopts …
