TIANAO LI ęŽå¤©éŖœ

I'm a senior undergraduate student majoring in Electronic Engineering at Tsinghua University. I'm currently a research intern at the Bio Inspired Vision Lab, at Northwestern University, advised by Prof. Emma Alexander. My research interest lies at the intersection of computational imaging, computer vision, signal processing, optimization, and machine learning. Iā€™m especially interested in solving inverse problems in imaging, physics-informed machine learning, and astronomical imaging. I was previously a research assistant at the Tsinghua Visual Intelligence and Computational Imaging Lab.

I graduated from Beijing No.4 High School in 2019.

Outside of research, I enjoy playing basketball and amateur astronomy. I spent three wonderful years at the Tsinghua Astronomy Society as a core member. I'm also a huge fan of the Golden State Warriors šŸ†šŸ†šŸ†šŸ† the HARRY POTTER series.

I'm looking for a PhD opportunity starting from fall 2023.

    dise Galaxy Image Deconvolution for Weak Gravitational Lensing
    with Unrolled Plug-and-Play ADMM

    [Project Page] [Paper] [Video] [Code] [Dataset]

    We introduce a physics-informed deep learning approach to the Point Spread Function (PSF) deconvolution problem in galaxy surveys.

    Projects
    dise Fire Detection
    [Code]

    This is a non-deep learning fire detection pipeline inspired by this paper. Our pipeline comprises of three parts: color space classifier, color component classifier and texture classifier. Our model was trained and tested on the BoWFire Dataset and is able to detect fire from static images with an accuracy of 80%.

    dise Exoplanet Transit Photometry for TESS Planetary Candidates TOI-4439.01 & TOI-5278.01
    [Code] [Paper]

    The Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission led by MIT and NASA in search of exoplanets. A certain number of planet candidates (PC) discovered by TESS are not actual transiting exoplanets, which are usually referred as "false positives", therefore follow-up ground-based photometry is performed for verifications. We conduct ground-based transit photometry on two planets candidates declared in TESS, TOI-5278.01 and TOI-4439.01 with an 80cm telescope at Xinglong Observatory, P.R. China. Our data processing pipeline comprises of three parts: image reduction, aperture photometry and EXOFAST fit. For TOI-4439.01, our result is in accordance with TESS data, proving the exoplanet nature, while the EXOFAST fit did not converge for TOI-5278.01 due to low SNR of the light curve.

    dise dise Video-Audio Signal Processing
    [Code]

    Developed three algorithms that solve the following problems respectively:
    1. Recognize faces from videos clips.
    2. Recongizes voices from audios.
    3. Given a video of three speakers speaking at the same time, separate the speeches from the three speakers.
    This project is implemented in Python with the aid of Face Recognition, Resemblyzer and Speechbrain.

    dise Astro Image Processing
    [Code & Data]

    This repo contains my code and data for astronomical image reduction. The images were taken at Huairou, Beijing with a 25cm telescope of DoA. Targets include M13, M51, M3, etc.

    dise Video Editing Based on Rhythm Matching
    [Code] [Video]

    Developed an algorithm to create a video from a given set of video clips and a piece of background music to best match the clips' audio rhythm with the background music. This project is implemented with Matlab.

    dise Stock Forecast with GPR
    [Code]

    Built an algorithm using Guassian Process Regression to predict the stock prices from previous observations. This project is implemented with Python and Scikit Learn.
