Object Remover Performance Evaluation Methods using Class-wise Object Removal Images

no code implementations17 Apr 2024 Changsuk Oh, Dongseok Shim, Taekbeom Lee, H. Jin Kim

In this letter, to validate the current evaluation methods cannot properly evaluate the performance of an object remover, we create a dataset with object removal ground truth and compare the evaluations made by the current methods using original images to those utilizing object removal ground truth images.

SNeRL: Semantic-aware Neural Radiance Fields for Reinforcement Learning

no code implementations27 Jan 2023 Dongseok Shim, Seungjae Lee, H. Jin Kim

As previous representations for reinforcement learning cannot effectively incorporate a human-intuitive understanding of the 3D environment, they usually suffer from sub-optimal performances.

Learning a Geometric Representation for Data-Efficient Depth Estimation via Gradient Field and Contrastive Loss

1 code implementation6 Nov 2020 Dongseok Shim, H. Jin Kim

In this paper, we show that existing self-supervised methods do not perform well on depth estimation and propose a gradient-based self-supervised learning algorithm with momentum contrastive loss to help ConvNets extract the geometric information with unlabeled images.
