No More Discrimination: Cross City Adaptation of Road Scene Segmenters

9 code implementations ICCV 2017 Yi-Hsin Chen, Wei-Yu Chen, Yu-Ting Chen, Bo-Cheng Tsai, Yu-Chiang Frank Wang, Min Sun

Despite the recent success of deep-learning based semantic segmentation, deploying a pre-trained road scene segmenter to a city whose images are not presented in the training set would not achieve satisfactory performance due to dataset biases.

EmotionX-IDEA: Emotion BERT -- an Affectional Model for Conversation

1 code implementation17 Aug 2019 Yen-Hao Huang, Ssu-Rui Lee, Mau-Yun Ma, Yi-Hsin Chen, Ya-Wen Yu, Yi-Shin Chen

By the nature of the framework of BERT, a two-sentence structure, we adapt BERT to continues dialogue emotion prediction tasks, which rely heavily on the sentence-level context-aware understanding.

Generation of sub-MHz and spectrally-bright biphotons from hot atomic vapors with a phase mismatch-free scheme

no code implementations9 Dec 2020 Chia-Yu Hsu, Yu-Sheng Wang, Jia-Mou Chen, Fu-Chen Huang, Yi-Ting Ke, Emily Kay Huang, Weilun Hung, Kai-Lin Chao, Shih-Si Hsiao, Yi-Hsin Chen, Chih-Sung Chuu, Ying-Cheng Chen, Yong-Fan Chen, Ite A. Yu

The generation rate per linewidth of the 610-kHz biphoton source is 1, 500 pairs/(s$\cdot$MHz), which is the best result of all the sub-MHz biphoton sources in the literature.

Video Rescaling Networks with Joint Optimization Strategies for Downscaling and Upscaling

1 code implementation CVPR 2021 Yan-Cheng Huang, Yi-Hsin Chen, Cheng-You Lu, Hui-Po Wang, Wen-Hsiao Peng, Ching-Chun Huang

Our Long Short-Term Memory Video Rescaling Network (LSTM-VRN) leverages temporal information in the low-resolution video to form an explicit prediction of the missing high-frequency information for upscaling.

B-CANF: Adaptive B-frame Coding with Conditional Augmented Normalizing Flows

1 code implementation5 Sep 2022 Mu-Jung Chen, Yi-Hsin Chen, Wen-Hsiao Peng

Our B*-frames allow greater flexibility in specifying the group-of-pictures (GOP) structure by reusing the B-frame codec to mimic P-frame coding, without the need for an additional, separate P-frame codec.

Transformer-based Variable-rate Image Compression with Region-of-interest Control

1 code implementation18 May 2023 Chia-Hao Kao, Ying-Chieh Weng, Yi-Hsin Chen, Wei-Chen Chiu, Wen-Hsiao Peng

Our prompt generation networks generate content-adaptive tokens according to the input image, an ROI mask, and a rate parameter.

MoTIF: Learning Motion Trajectories with Local Implicit Neural Functions for Continuous Space-Time Video Super-Resolution

1 code implementation ICCV 2023 Si-Cun Chen, Yi-Hsin Chen, Yen-Yu Lin, Wen-Hsiao Peng

We motivate the use of forward motion from the perspective of learning individual motion trajectories, as opposed to learning a mixture of motion trajectories with backward motion.

Transformer-based Learned Image Compression for Joint Decoding and Denoising

no code implementations20 Feb 2024 Yi-Hsin Chen, Kuan-Wei Ho, Shiau-Rung Tsai, Guan-Hsun Lin, Alessandro Gnutti, Wen-Hsiao Peng, Riccardo Leonardi

Instead of training separate decoders for these tasks, we incorporate two add-on modules to adapt a pre-trained image decoder from performing the standard image reconstruction to joint decoding and denoising.
