Elite360D: Towards Efficient 360 Depth Estimation via Semantic- and Distance-Aware Bi-Projection Fusion

no code implementations25 Mar 2024 Hao Ai, Lin Wang

With a flexible ERP image encoder, it includes an ICOSAP point encoder, and a Bi-projection Bi-attention Fusion (B2F) module (totally ~1M parameters).

Dream360: Diverse and Immersive Outdoor Virtual Scene Creation via Transformer-Based 360 Image Outpainting

no code implementations19 Jan 2024 Hao Ai, Zidong Cao, Haonan Lu, Chen Chen, Jian Ma, Pengyuan Zhou, Tae-Kyun Kim, Pan Hui, Lin Wang

To this end, we propose a transformer-based 360 image outpainting framework called Dream360, which can generate diverse, high-fidelity, and high-resolution panoramas from user-selected viewports, considering the spherical properties of 360 images.

Stable Diffusion Reference Only: Image Prompt and Blueprint Jointly Guided Multi-Condition Diffusion Model for Secondary Painting

1 code implementation4 Nov 2023 Hao Ai, Lu Sheng

Therefore, we present a new method in this paper, Stable Diffusion Reference Only, a images-to-image self-supervised model that uses only two types of conditional images for precise control generation to accelerate secondary painting.

OmniZoomer: Learning to Move and Zoom in on Sphere at High-Resolution

no code implementations ICCV 2023 Zidong Cao, Hao Ai, Yan-Pei Cao, Ying Shan, XiaoHu Qie, Lin Wang

The M\"obius transformation is typically employed to further provide the opportunity for movement and zoom on ODIs, but applying it to the image level often results in blurry effect and aliasing problem.

360$^\circ$ High-Resolution Depth Estimation via Uncertainty-aware Structural Knowledge Transfer

no code implementations17 Apr 2023 Zidong Cao, Hao Ai, Athanasios V. Vasilakos, Lin Wang

Our key idea is to transfer the scene structural knowledge from the HR image modality and the corresponding LR depth maps to achieve the goal of HR depth estimation without any extra inference cost.

HRDFuse: Monocular 360°Depth Estimation by Collaboratively Learning Holistic-with-Regional Depth Distributions

no code implementations21 Mar 2023 Hao Ai, Zidong Cao, Yan-Pei Cao, Ying Shan, Lin Wang

Depth estimation from a monocular 360{\deg} image is a burgeoning problem owing to its holistic sensing of a scene.

Deep Learning for Omnidirectional Vision: A Survey and New Perspectives

1 code implementation21 May 2022 Hao Ai, Zidong Cao, Jinjing Zhu, Haotian Bai, Yucheng Chen, Lin Wang

Omnidirectional image (ODI) data is captured with a 360x180 field-of-view, which is much wider than the pinhole cameras and contains richer spatial information than the conventional planar images.
