Academic Papers


Pedestrian Detection Using Lidar

Final paper written for EECS442 class. Used correlated Lidar and image dataset to identify pedestrians through segmentation, feature extraction, classification, and filtering. (Fall 2016) [paper] [lidar-img-objectDetection repo]



Speaker Diarization using MFCCs

This is the final project website for EECS351. Performed speaker diarization using Mel Frequency Cepstrum Coefficients (MFCCs) and Mahalanobis distance. Also explored envelope features and kth nearest neighbor algorithms. (Fall 2016) [website] [eecs351project repo]


Signpost LoRa Communications

The signpost project was a Lab11 project with the goal of putting modular computers (sensors could be simply plugged in) on signposts, with the goal of enabling city scale sensing. Was responsible for choice of the LoRa module, configuration of LoRa transmission parameters, and creation of a Node.JS library (iM880-serial-comm) to interface with the module. (2016) [LoRa-comms repo] [iM880-serial-comm repo]



This is the GitHub repository for the SensEye-2 project. Goal was real-time gaze detection of a human eye using a pair of glasses with low-power cameras mounted facing inward and outward. This information let the system determine where the eye was looking and whether the gaze was shifting. (2015-2016) [SensEye-2 repo]


A Novel Beamforming Approach to Stereo Sound

Designed a new beamforming approach for near-field applications (less than one meter) to create true stereo sound. Signals were time-delayed in order to converge on each ear of the user and create lobes of sound, instead of creating a traditional beamforming wave-front. See the paper submitted to the Intel Science Talent Search and Siemens Competition in fall 2013, a webpage created in 2014 for my TJHSST Senior Project and the GitHub repository with the project source code.
