Python Developer in Washington, DC, United States
Software Engineer2009 - PRESENTUnited States Government
Technologies: Linux, C++, Python, SQL
- Created an automated tool to detect and extract text from videos in real-time using C++, OpenCV, support vector machines, and a novel representation of the text space.
- Built an organization-wide Linux file-system that allows all data to be tracked, properly categorized, and legally compliant—meeting government requirements for the data storage of critical information.
- Developed an automated system for the machine language translation of small phrases that filled a need not satisfied by either simple word lookup or more advanced translation of full sentences.
- Wrote Python scripts to support the automated processing of complex tasks for non-technical customers.
- Served as the team lead for a vital tiger team that required understanding several different skill sets.
- Received several team awards, two invention awards, and a patent.
Associate Professor of Computer Science1999 - 2009Texas Tech University
Technologies: C/C++, Python, Computer Vision, Computer Graphics, Robotics, Scientific Computing, Pattern Matching
- Worked as the founding director of the Data Representation and Intelligent Learning Lab and supervised twenty masters students and two PhD students.
- Taught courses on programming, analysis of algorithms, operating systems, numerical methods, computer graphics, computer visualization, pattern recognition, and computer vision.
- Developed a novel method for estimating livestock body mass from laser imaging that resulted in licensing and commercialization of the technology.
- Created a novel method for improving the shape reconstruction from multiple images using an improved data analysis of the neighborhoods around critical points inside of an image. This technology was also licensed for commercialization.
- Built a computer vision library to support complex mathematical operations on geometric objects that wrapped fast Fortran code underneath a clean object-oriented library in C/C++.
Research Engineer1998 - 1999Summus, Ltd
Technologies: C/C++, Assembly Language, Wavelet Theory
- Worked as a developer on a video compression team that was designated as the leader in the video-compression quality in bandwidth limited environments.
- Invented a new method that improved the accuracy of underwater mine detection by 95% by detecting surface slope of ocean waves and removing the effects of light refraction. This resulted in a technology that received the award of 1999 Advanced Imaging Solution of Year.
- Wrote real-time, cinema-quality, video-compression code for applications with high bandwidth.
- Optimized the code by detecting code bottlenecks and replacing expensive functions with numerical approximations implemented in x86 Assembly. This resulted in a 20-time speed-up of the specific functions, and a 3-time speed-up of the overall compressor.
- Flatland (Development)
Created a system for the archaeological records of 3D scanned historical objects. Although the data was 3D, the archaeologists were more comfortable with 2D printings. Geo-rectified the 3D data to a cardinal 2D coordinate system and unwrapped 360 degree views into a flat representation allowing archaeological preservation of national park landmarks.
- Object Recognition for Crew Exploration Vehicle (Development)
While working as a visiting scientist at NASA, developed a system for real-time recognition of complex 3D shapes. Relied upon the crew exploration vehicle only having a small set of objects predetermined prior to launch, then developed shape classifiers for each object based upon surface characteristics of each shape.
