Blur2Blur: Blur Conversion for Unsupervised Image Deblurring on Unknown Domains

no code implementations24 Mar 2024 Bang-Dang Pham, Phong Tran, Anh Tran, Cuong Pham, Rang Nguyen, Minh Hoai

This algorithm works by transforming a blurry input image, which is challenging to deblur, into another blurry image that is more amenable to deblurring.

HyperCUT: Video Sequence from a Single Blurry Image using Unsupervised Ordering

1 code implementation CVPR 2023 Bang-Dang Pham, Phong Tran, Anh Tran, Cuong Pham, Rang Nguyen, Minh Hoai

We consider the challenging task of training models for image-to-video deblurring, which aims to recover a sequence of sharp images corresponding to a given blurry image input.

Single-Image HDR Reconstruction by Multi-Exposure Generation

1 code implementation28 Oct 2022 Phuoc-Hieu Le, Quynh Le, Rang Nguyen, Binh-Son Hua

In this work, we propose a weakly supervised learning method that inverts the physical image formation process for HDR reconstruction via learning to generate multiple exposures from a single image.

PSENet: Progressive Self-Enhancement Network for Unsupervised Extreme-Light Image Enhancement

2 code implementations3 Oct 2022 Hue Nguyen, Diep Tran, Khoi Nguyen, Rang Nguyen

The extremes of lighting (e. g. too much or too little light) usually cause many troubles for machine and human vision.

POODLE: Improving Few-shot Learning via Penalizing Out-of-Distribution Samples

1 code implementation NeurIPS 2021 Duong H. Le, Khoi D. Nguyen, Khoi Nguyen, Quoc-Huy Tran, Rang Nguyen, Binh-Son Hua

In this work, we propose to use out-of-distribution samples, i. e., unlabeled samples coming from outside the target classes, to improve few-shot learning.

TISE: Bag of Metrics for Text-to-Image Synthesis Evaluation

1 code implementation2 Dec 2021 Tan M. Dinh, Rang Nguyen, Binh-Son Hua

Our study outlines several issues in the current evaluation pipeline: (i) for image quality assessment, a commonly used metric, e. g., Inception Score (IS), is often either miscalibrated for the single-object case or misused for the multi-object case; (ii) for text relevance and object accuracy assessment, there is an overfitting phenomenon in the existing R-precision (RP) and Semantic Object Accuracy (SOA) metrics, respectively; (iii) for multi-object case, many vital factors for evaluation, e. g., object fidelity, positional alignment, counting alignment, are largely dismissed; (iv) the ranking of the methods based on current metrics is highly inconsistent with real images.

HyperInverter: Improving StyleGAN Inversion via Hypernetwork

1 code implementation CVPR 2022 Tan M. Dinh, Anh Tuan Tran, Rang Nguyen, Binh-Son Hua

In the first phase, we train an encoder to map the input image to StyleGAN2 $\mathcal{W}$-space, which was proven to have excellent editability but lower reconstruction quality.

Group-Theme Recoloring for Multi-Image Color Consistency

1 code implementation Pacific Graphics 2017 Rang Nguyen, Brian Price, Scott Cohen, and Michael S. Brown

Methods such as color transfer are effective in making an image share similar colors with a target image; however, color transfer is not suitable for modifying multiple images.

Illuminant Aware Gamut-Based Color Transfer

1 code implementation Pacific Graphics 2014 Rang Nguyen, Seon Joo Kim, Michael S. Brown

Our method is unique in its considera- tion of the scene illumination and the constraint that the mapped image must be within the color gamut of the target image.

Raw-to-Raw: Mapping between Image Sensor Color Responses

no code implementations CVPR 2014 Rang Nguyen, Dilip K. Prasad, Michael S. Brown

We show that this approach achieves state-of-the-art results on a range of consumer cameras and images of arbitrary scenes and illuminations.
