Deep Camera Obscura: An Image Restoration Pipeline for Lensless Pinhole Photography

no code implementations12 Aug 2021 Joshua D. Rego, Huaijin Chen, Shuai Li, Jinwei Gu, Suren Jayasuriya

The lensless pinhole camera is perhaps the earliest and simplest form of an imaging system using only a pinhole-sized aperture in place of a lens.

Removing Diffraction Image Artifacts in Under-Display Camera via Dynamic Skip Connection Network

1 code implementation CVPR 2021 Ruicheng Feng, Chongyi Li, Huaijin Chen, Shuai Li, Chen Change Loy, Jinwei Gu

Recent development of Under-Display Camera (UDC) systems provides a true bezel-less and notch-free viewing experience on smartphones (and TV, laptops, tablets), while allowing images to be captured from the selfie camera embedded underneath.

iToF2dToF: A Robust and Flexible Representation for Data-Driven Time-of-Flight Imaging

no code implementations12 Mar 2021 Felipe Gutierrez-Barragan, Huaijin Chen, Mohit Gupta, Andreas Velten, Jinwei Gu

Recently, data-driven methods that jointly denoise and mitigate MPI have become state-of-the-art without using the intermediate transient representation.

JPAD-SE: High-Level Semantics for Joint Perception-Accuracy-Distortion Enhancement in Image Compression

no code implementations24 May 2020 Shiyu Duan, Huaijin Chen, Jinwei Gu

In this paper, we (1) present a generic framework that can enable any image codec to leverage high-level semantics, and (2) study the joint optimization of perception quality, accuracy of downstream computer vision task, and distortion.

Fast Retinomorphic Event Stream for Video Recognition and Reinforcement Learning

no code implementations16 May 2018 Wanjia Liu, Huaijin Chen, Rishab Goel, Yuzhong Huang, Ashok Veeraraghavan, Ankit Patel

Good temporal representations are crucial for video understanding, and the state-of-the-art video recognition framework is based on two-stream networks.

Online Reweighted Least Squares Algorithm for Sparse Recovery and Application to Short-Wave Infrared Imaging

no code implementations29 Jun 2017 Subhadip Mukherjee, Deepak R., Huaijin Chen, Ashok Veeraraghavan, Chandra Sekhar Seelamantula

The proposed online algorithm is useful in a setting where one seeks to design a progressive decoding strategy to reconstruct a sparse signal from linear measurements so that one does not have to wait until all measurements are acquired.

Compressive Holographic Video

no code implementations27 Oct 2016 Zihao Wang, Leonidas Spinoulas, Kuan He, Huaijin Chen, Lei Tian, Aggelos K. Katsaggelos, Oliver Cossairt

Compressive holography has been introduced as a method that allows 3D tomographic reconstruction at different depths from a single 2D image.
