Research Interests.
My research interests lie at the intersection of Deep Learning, Computer Vision, 3D Geometry and their applications in Augmented Reality and Robotics. I enjoy studying how deep learning can be applied to computer vision problems including keypoint detection, image matching, relocalization, multi-view reconstruction, visual SLAM, depth estimation, homography estimation, camera calibration and bundle-adjustment.

Bio.
As a member of the AI Research Team at Magic Leap I worked on developing new deep learning-based methods for Visual Simultaneous Localization and Mapping (Visual SLAM) and Structure-from-Motion (SfM). I was co-advised by Tomasz Malisiewicz and Andrew Rabinovich and authored publications at top-tier conferences including CVPR and RSS (e.g. Deep Homography Estimation, SuperPoint and SuperGlue). I also pioneered computer vision algorithms which were ultimately deployed on the ML1 headset. Prior to Magic Leap, I received my Master's and Bachelor's degrees at the University of Michigan, where I studied Machine Learning, Computer Vision and Robotics. During my studies I worked on various small projects in areas such as person tracking, outdoor SLAM and 3D ConvNets.

SuperGlue: Learning Feature Matching with Graph Neural Networks
This paper introduces SuperGlue, a neural network that matches two sets of local features by jointly finding correspondences and rejecting non-matchable points. Assignments are estimated by solving a differentiable optimal transport problem, whose costs are predicted by a graph neural network. We introduce a flexible context aggregation mechanism based on attention, enabling SuperGlue to reason about the underlying 3D scene and feature assignments jointly.

Deep ChArUco: Dark ChArUco Marker Pose Estimation
We present a real-time pose estimation system which combines two custom deep networks, ChArUcoNet and RefineNet, with the Perspective-n-Point algorithm to estimate the marker's 6DoF pose. ChArUcoNet is a convolutional neural network which jointly outputs ID-specific classifiers and 2D point locations. The 2D point locations are further refined into subpixel coordinates using RefineNet. We evaluate Deep ChArUco in challenging scenarios and demonstrate that our approach is superior to a traditional OpenCV-based method.

Self-Improving Visual Odometry
We propose a self-supervised learning framework that uses unlabeled monocular video sequences to generate large-scale supervision for training a Visual Odometry (VO) frontend. Our proposed frontend consists of a single multi-task CNN which outputs 2D keypoints locations, keypoint descriptors, and a novel point stability score. When trained using VO at scale on 2.5 million images, the stability classifier automatically discovers a ranking for keypoints that are not likely to help in VO, such as t-junctions across depth discontinuities, features on shadows and highlights, and dynamic objects like people.

SuperPoint: Self-Supervised Interest Point Detection and Description
This work presents a self-supervised framework for training interest point detectors and descriptors suitable for a large number of multiple-view geometry problems in computer vision. As opposed to patch-based neural networks, our fully-convolutional model operates on full-sized images and jointly computes pixel-level interest point locations and associated descriptors in one forward pass. Our model, when trained on the MS-COCO image dataset, is able to repeatedly detect a rich set of interest points and stably track them over time.

Toward Geometric Deep SLAM
We present a point tracking system powered by two CNNs. The first network, MagicPoint, operates on single images and extracts salient 2D points. As transformation estimation is more simple when the detected points are geometrically stable, we designed a second network, MagicWarp, which operates on pairs of point images and estimates the homography that relates the inputs.

Deep Image Homography Estimation
We present a deep convolutional neural network called HomographyNet for estimating the relative homography between a pair of images. We use a 4-point homography parameterization which maps the four corners from one image into the second image. The network is trained end-to-end using warped MS-COCO images, allow the use of large-scale training without time-consuming data collection. The HomographyNet does not require separate local feature detection and transformation estimation stages and outperforms a traditional homography estimator based on ORB.

Simultaneous Environment Discovery & Annotation
SEDA is a project for enhancing human learning by using state of the art techniques from AI. The non-technically constrained goal is to create an overlay to human vision to help with tasks humans are inherently bad at such as memory, calculations, and abstractions and to help speed up tasks such as looking up information and referencing material.

Robust Locally Weighted Regression for Aesthetically Pleasing Region-of-Interest Video Generation
We provide a method that takes the output from an object tracker and creates a smoothed RoI to be viewed as the final output video. To accomplish this, we use a variation of linear regression, namely, robust locally weighted linear regression (rLWLR-Smooth).

Parallel Tracking and Mapping for Outdoor Localization
By removing some of the long term pose optimizations and by limiting the allowed number of bundle adjustment iterations, I was able to modify PTAM to work in an outdoor localization setting. This work was used to help improve the accuracy of a multi-target tracking system.

Robotics Competition for Autonomous SLAM and Path Planning
We entered a mobile robot, equipped with a fisheye camera and laser pointer, in a robotics competition. To win, the robot must autonomously map a small area, shoot green triangles, and return to a starting point. We implemented a fast agglomerative line fitting algorithm, a graph-based SLAM algorithm, and a memory efficient quad-tree for map storage. Our team finished 2nd out of 8 teams.

Projectile Prediction and Robotic Retrieval using Kinect RGBD Video
We developed a fully automated projectile-catching robot by affixing a small basket to a mobile robot and predicting the projectile's landing position in real-time. We implemented a detection algorithm using RGBD video from a Kinect and an estimation algorithm using linear regression. Once the landing position was calculated, we used dead-reckoning and a PID controller to navigate the mobile robot.

Tracking-by-detection in a Lecture Hall Setting
We present a framework for tracking a single human (person-of-interest) in a lecture hall environment. It is a tracking-by-detection framework that uses a generic person detector, a novel scoring function to solve the data association problem, and a Kalman filter that provides reliable state estimation. In our scoring function, we introduce two novel subcomponents: a subscore based on the target’s width and a subscore based on the color histogram of him/her at the first time step.

Linear array of photodiodes to track a human speaker for video recording
We present a human lecturer tracking and recording system that consists of a pan/tilt/zoom (PTZ) color video camera, a necklace of infrared LEDs and a linear photodiode array detector. Electronic output from the photodiode array is processed to generate the location of the LED necklace, which is worn by a human speaker. The LED necklace is flashed at 70Hz at a 50% duty cycle to provide noise-filtering capability.
