Just Add $100 More: Augmenting NeRF-based Pseudo-LiDAR Point Cloud for Resolving Class-imbalance Problem

no code implementations18 Mar 2024 Mincheol Chang, Siyeong Lee, Jinkyu Kim, Namil Kim

Typical LiDAR-based 3D object detection models are trained in a supervised manner with real-world data collection, which is often imbalanced over classes (or long-tailed).

Painting Outside as Inside: Edge Guided Image Outpainting via Bidirectional Rearrangement with Progressive Step Learning

no code implementations5 Oct 2020 Kyunghun Kim, Yeohun Yun, Keon-Woo Kang, Kyeongbo Kong, Siyeong Lee, Suk-Ju Kang

The bidirectional boundary region rearrangement enables the generation of the missing region using bidirectional information similar to that of the image inpainting task, thereby generating the higher quality than the conventional methods using unidirectional information.

End-to-End Differentiable Learning to HDR Image Synthesis for Multi-exposure Images

1 code implementation29 Jun 2020 Jung Hee Kim, Siyeong Lee, Suk-Ju Kang

We tackle the problem in stack reconstruction-based methods by proposing a novel framework with a fully differentiable high dynamic range imaging (HDRI) process.

Deep Recursive HDRI: Inverse Tone Mapping using Generative Adversarial Networks

1 code implementation ECCV 2018 Siyeong Lee, Gwon Hwan An, Suk-Ju Kang

Because most images have a low dynamic range, recovering the lost dynamic range from a single low dynamic range image is still prevalent.

Deep Chain HDRI: Reconstructing a High Dynamic Range Image from a Single Low Dynamic Range Image

no code implementations19 Jan 2018 Siyeong Lee, Gwon Hwan An, Suk-Ju Kang

The proposed model is based on a convolutional neural network composed of dilated convolutional layers, and infers LDR images with various exposures and illumination from a single LDR image of the same scene.
