Universal Compressed Image Restoration via Codec-Aware Conditioning with Reinforcement Learning

Changwoo Han, Hongil Kim, Donghyun Kim, Sung-Chang Lim, Seung-Won Jung

AAAI 2026technical

We address the task of universal compressed image restoration, which involves recovering high-quality images degraded by a wide range of codecs and compression levels. While prior methods have made significant progress, they typically target specific degradation types and struggle to generalize acro

Streaming End-to-End Speech Recognition with Jointly Trained Neural Feature Enhancement

Chanwoo Kim, Abhinav Garg, Dhananjaya Gowda, Seongkyu Mun, Changwoo Han

ICASSP 2021accepted

In this paper, we present a streaming end-to-end speech recognition model based on Monotonic Chunkwise Attention (MoCha) jointly trained with enhancement layers. Even though the MoCha attention enables streaming speech recognition with recognition accuracy comparable to a full attention-based approa…
