Neural Radiance Fields for Transparent Object Using Visual Hull

no code implementations13 Dec 2023 Heechan Yoon, Seungkyu Lee

Unlike opaque object, novel view synthesis of transparent object is a challenging task, because transparent object refracts light of background causing visual distortions on the transparent object surface along the viewpoint change.

Single Image Reflection Removal with Reflection Intensity Prior Knowledge

no code implementations6 Dec 2023 Dongshen Han, Seungkyu Lee, Chaoning Zhang, Heechan Yoon, Hyukmin Kwon, HyunCheol Kim, HyonGon Choo

In this paper, we propose a general reflection intensity prior that captures the intensity of the reflection phenomenon and demonstrate its effectiveness.

Internal-External Boundary Attention Fusion for Glass Surface Segmentation

no code implementations1 Jul 2023 Dongshen Han, Seungkyu Lee, Chaoning Zhang, Heechan Yoon, Hyukmin Kwon, Hyun-Cheol Kim, Hyon-Gon Choo

Inspired by prior semantic segmentation approaches with challenging image types such as X-ray or CT scans, we propose separated internal-external boundary attention modules that individually learn and selectively integrate visual characteristics of the inside and outside region of glass surface from a single color image.

Faster Segment Anything: Towards Lightweight SAM for Mobile Applications

2 code implementations25 Jun 2023 Chaoning Zhang, Dongshen Han, Yu Qiao, Jung Uk Kim, Sung-Ho Bae, Seungkyu Lee, Choong Seon Hong

Concretely, we distill the knowledge from the heavy image encoder (ViT-H in the original SAM) to a lightweight image encoder, which can be automatically compatible with the mask decoder in the original SAM.

Unrealistic Feature Suppression for Generative Adversarial Networks

no code implementations23 Jul 2021 Sanghun Kim, Seungkyu Lee

However, sampling approaches which discard samples show limitations in some aspects such as the speed of training and optimality of the networks.

Spatially Decomposed Hinge Adversarial Loss by Local Gradient Amplifier

no code implementations1 Jan 2021 Sanghun Kim, Seungkyu Lee

Generative Adversarial Networks (GANs) have achieved large attention and great success in various research areas, but it still suffers from training instability.

Continual learning with neural activation importance

no code implementations1 Jan 2021 Sohee Kim, Seungkyu Lee

Continual learning is a concept of online learning along with multiple sequential tasks.

Sub-clusters of Normal Data for Anomaly Detection

no code implementations17 Nov 2020 Gahye Lee, Seungkyu Lee

We hypothesize that if there exists reasonably good feature space semantically separating sub-clusters of given normal data, unseen anomaly also can be well distinguished in the space from the normal data.

Mode Penalty Generative Adversarial Network with adapted Auto-encoder

no code implementations16 Nov 2020 Gahye Lee, Seungkyu Lee

To this end, generator network of GAN learns implicit distribution of real data set from the classification with candidate generated samples.

Small Noisy and Perspective Face Detection using Deformable Symmetric Gabor Wavelet Network

no code implementations30 Oct 2020 Sherzod Salokhiddinov, Seungkyu Lee

Face detection and tracking in low resolution image is not a trivial task due to the limitation in the appearance features for face characterization.
