Extended JPEG Decoders With Luma Restoration and Luma-Guided Chroma Restorations
Koushi Yamazaki, Taizo Suzuki · 2021 IEEE 10th Global Conference on Consumer Electronics (GCCE) · 2021
This study presents two extended JPEG decoders that restore the degraded images quickly and accurately. They have a luma restoration and two luma-guided chroma restorations before/after chroma upsampling in addition to the standard decoder. The experiments based on the typical classical methods such as the block-matching and 3D filtering (BM3D) and guided filter (GF) show that the proposed methods restore the noise-added JPEG-compressed images faster and better than the classical one that does not consider the JPEG process.
