Projects

  • Database System Implementation

    -

    Developed a query execution engine which receives a simplified XQuery and an input XML file and evaluates the query. The system parses the query into an abstract tree representation (using ANTLR4), optimizes it (using hash-based join), produces a list of output nodes, and constructs a result file in the form of XML.

  • Digital Vision Screening

    -

    Worked with the Shiley Eye Center to provide an accurate and reliable system that identifies children with eye problems that include amblyopia, strabismus, astigmatism, anisometropia, etc. Developed and implemented algorithms that detect refractive errors from images of red eyes.
    Technologies used: OpenCV, Visual Studio C++

  • p4shelve with Jenkins - Hackathon Project

    -

    Used p4 shelve in Jenkins to tell whether the commit breaks the builds before pushing the code to production.
    Technologies used: Perforce, Jenkins, bash

  • Photo Filter WebApp

    -

    Implemented a mobile web application using jQuery that allows users to transform multiple photos into different themes, add text, comment, and share them on social platforms. The app also comes with a photo gallery that displays photos from the user's own facebook or flickr account. The resulting photos will be uploaded on the preferred platform without requesting users to log in again.
    Technologies used: HTML, CSS, JQuery, C++

  • System Measurement Project

    -

    Implemented and performed a series of experiments to measure the performance of Ubuntu 13.10 on a Dell Studio XPS 13” with Intel(R) Core(TM)2 Duo CPU P8600 @2.40GHz
    The measurements included 4 categories:
    - CPU, Scheduling, and OS Services: task creation overhead, context switch overhead, etc.
    - Memory: RAM access time, page fault service time, etc.
    - Network: RTT, connection overhead, etc.
    - File System: file read time, contention overhead, etc.

  • Systolic Pressure Estimation Using Video Processing

    -

    Designed and implemented a low-cost and convenient method to estimate systolic pressure using video processing. The method extracts pulse transit time between the neck and the wrist using video processing, which includes feature extraction, feature tracking, temporal filtering, principle component analysis, etc. After obtaining the pulse transit time, linear regression analysis is done to estimate systolic blood pressure.
    Technologies used: Matlab, Harris Corner detection, Lucas-Kanade…
