Switch Diffusion Transformer: Synergizing Denoising Tasks with Sparse Mixture-of-Experts

1 code implementation14 Mar 2024 Byeongjun Park, Hyojun Go, Jin-Young Kim, Sangmin Woo, Seokil Ham, Changick Kim

To achieve this, we employ a sparse mixture-of-experts within each transformer block to utilize semantic information and facilitate handling conflicts in tasks through parameter isolation.

HarmonyView: Harmonizing Consistency and Diversity in One-Image-to-3D

1 code implementation26 Dec 2023 Sangmin Woo, Byeongjun Park, Hyojun Go, Jin-Young Kim, Changick Kim

This work introduces HarmonyView, a simple yet effective diffusion sampling technique adept at decomposing two intricate aspects in single-image 3D generation: consistency and diversity.

DiffRef3D: A Diffusion-based Proposal Refinement Framework for 3D Object Detection

no code implementations25 Oct 2023 Se-Ho Kim, Inyong Koo, Inyoung Lee, Byeongjun Park, Changick Kim

During training, DiffRef3D gradually adds noise to the residuals between proposals and target objects, then applies the noisy residuals to proposals to generate hypotheses.

Point-DynRF: Point-based Dynamic Radiance Fields from a Monocular Video

no code implementations14 Oct 2023 Byeongjun Park, Changick Kim

Dynamic radiance fields have emerged as a promising approach for generating novel views from a monocular video.

Denoising Task Routing for Diffusion Models

2 code implementations11 Oct 2023 Byeongjun Park, Sangmin Woo, Hyojun Go, Jin-Young Kim, Changick Kim

Diffusion models generate highly realistic images by learning a multi-step denoising process, naturally embodying the principles of multi-task learning (MTL).

Bridging Implicit and Explicit Geometric Transformation for Single-Image View Synthesis

no code implementations15 Sep 2022 Byeongjun Park, Hyojun Go, Changick Kim

Although recent methods generate high-quality novel views, synthesizing with only one explicit or implicit 3D geometry has a trade-off between two objectives that we call the "seesaw" problem: 1) preserving reprojected contents and 2) completing realistic out-of-view regions.

Temporal Flow Mask Attention for Open-Set Long-Tailed Recognition of Wild Animals in Camera-Trap Images

no code implementations31 Aug 2022 JeongSoo Kim, Sangmin Woo, Byeongjun Park, Changick Kim

Camera traps, unmanned observation devices, and deep learning-based image recognition systems have greatly reduced human effort in collecting and analyzing wildlife images.

Residual-Guided Learning Representation for Self-Supervised Monocular Depth Estimation

no code implementations8 Nov 2021 Byeongjun Park, Taekyung Kim, Hyojun Go, Changick Kim

In this paper, we propose residual guidance loss that enables the depth estimation network to embed the discriminative feature by transferring the discriminability of auto-encoded features.
