A Gated MLP Architecture for Learning Topological Dependencies in Spatio-Temporal Graphs

no code implementations29 Jan 2024 Yun Young Choi, Minho Lee, Sun Woo Park, Seunghwan Lee, Joohwan Ko

The Cy2Mixer is composed of three blocks based on MLPs: A message-passing block for encapsulating spatial information, a cycle message-passing block for enriching topological information through cyclic subgraphs, and a temporal block for capturing temporal properties.

DiffusionPoser: Real-time Human Motion Reconstruction From Arbitrary Sparse Sensors Using Autoregressive Diffusion

no code implementations31 Aug 2023 Tom Van Wouwe, Seunghwan Lee, Antoine Falisse, Scott Delp, C. Karen Liu

Unlike existing methods, our model grants users the flexibility to determine the number and arrangement of sensors tailored to the specific activity of interest, without the need for retraining.

NoiseTransfer: Image Noise Generation with Contrastive Embeddings

1 code implementation31 Jan 2023 Seunghwan Lee, Tae Hyun Kim

Although several real-world noisy datasets have been presented, the number of train datasets (i. e., pairs of clean and real noisy images) is limited, and acquiring more real noise datasets is laborious and expensive.

Generating 3D Bio-Printable Patches Using Wound Segmentation and Reconstruction to Treat Diabetic Foot Ulcers

no code implementations CVPR 2022 Han Joo Chae, Seunghwan Lee, Hyewon Son, Seungyeob Han, Taebin Lim

We introduce AiD Regen, a novel system that generates 3D wound models combining 2D semantic segmentation with 3D reconstruction so that they can be printed via 3D bio-printers during the surgery to treat diabetic foot ulcers (DFUs).

Cycled Compositional Learning between Images and Text

no code implementations24 Jul 2021 Jongseok Kim, Youngjae Yu, Seunghwan Lee, GunheeKim

Since this one-way mapping is highly under-constrained, we couple it with an inverse relation learning with the Correction Network and introduce a cycled relation for given Image We participate in Fashion IQ 2020 challenge and have won the first place with the ensemble of our model.

CurlingNet: Compositional Learning between Images and Text for Fashion IQ Data

1 code implementation27 Mar 2020 Youngjae Yu, Seunghwan Lee, Yuncheol Choi, Gunhee Kim

In order to learn an effective image-text composition for the data in the fashion domain, our model proposes two key components as follows.

Restore from Restored: Single Image Denoising with Pseudo Clean Image

no code implementations9 Mar 2020 Seunghwan Lee, Dongkyu Lee, Donghyeon Cho, Jiwon Kim, Tae Hyun Kim

However, these methods have limitations in using internal information available in a given test image.

Restore from Restored: Video Restoration with Pseudo Clean Video

no code implementations CVPR 2021 Seunghwan Lee, Donghyeon Cho, Jiwon Kim, Tae Hyun Kim

We analyze the restoration performance of the fine-tuned video denoising networks with the proposed self-supervision-based learning algorithm, and demonstrate that the FCN can utilize recurring patches without requiring accurate registration among adjacent frames.

Self-Supervised Fast Adaptation for Denoising via Meta-Learning

no code implementations9 Jan 2020 Seunghwan Lee, Donghyeon Cho, Jiwon Kim, Tae Hyun Kim

Under certain statistical assumptions of noise, recent self-supervised approaches for denoising have been introduced to learn network parameters without true clean images, and these methods can restore an image by exploiting information available from the given input (i. e., internal statistics) at test time.
