TexGen: Text-Guided 3D Texture Generation with Multi-view Sampling and Resampling

no code implementations2 Aug 2024 Dong Huo, Zixin Guo, Xinxin Zuo, Zhihao Shi, Juwei Lu, Peng Dai, Songcen Xu, Li Cheng, Yee-Hong Yang

For view consistent sampling, first of all we maintain a texture map in RGB space that is parameterized by the denoising step and updated after each sampling step of the diffusion model to progressively reduce the view discrepancy.

Learning to Recover Spectral Reflectance from RGB Images

1 code implementation4 Apr 2023 Dong Huo, Jian Wang, Yiming Qian, Yee-Hong Yang

Instead of relying on naive end-to-end training, we also propose a novel architecture that integrates the physical relationship between the spectral reflectance and the corresponding RGB images into the network based on our mathematical analysis.

Glass Segmentation with RGB-Thermal Image Pairs

1 code implementation12 Apr 2022 Dong Huo, Jian Wang, Yiming Qian, Yee-Hong Yang

Due to the large difference between the transmission property of visible light and that of the thermal energy through the glass where most glass is transparent to the visible light but opaque to thermal energy, glass regions of a scene are made more distinguishable with a pair of RGB and thermal images than solely with an RGB image.

Blind Non-Uniform Motion Deblurring using Atrous Spatial Pyramid Deformable Convolution and Deblurring-Reblurring Consistency

1 code implementation27 Jun 2021 Dong Huo, Abbas Masoumzadeh, Yee-Hong Yang

In this paper, we propose a new architecture which consists of multiple Atrous Spatial Pyramid Deformable Convolution (ASPDC) modules to deblur an image end-to-end with more flexibility.

Online Learnable Keyframe Extraction in Videos and its Application with Semantic Word Vector in Action Recognition

no code implementations25 Sep 2020 G M Mashrur E Elahi, Yee-Hong Yang

Instead, the important frames called keyframes not only are helpful in the recognition of an action but also can reduce the processing time of each video sequence for classification or in other applications, e. g. summarization.

Do-It-Yourself Single Camera 3D Pointer Input Device

1 code implementation12 Sep 2018 Bernard Llanos, Yee-Hong Yang

We present a new algorithm for single camera 3D reconstruction, or 3D input for human-computer interfaces, based on precise tracking of an elongated object, such as a pen, having a pattern of colored bands.

Underwater Camera Calibration Using Wavelength Triangulation

no code implementations CVPR 2013 Timothy Yau, Minglun Gong, Yee-Hong Yang

In underwater imagery, the image formation process includes refractions that occur when light passes from water into the camera housing, typically through a flat glass port.
