Timeframe: April 2011 - Present
Position Title: Systems Engineer Staff
Organization:
Missiles and Fire Control (MFC)
Strike Weapons
Long Range Anti-Ship Missile (LRASM)
Responsibilities:

Worked developing image processing and computational geometry algorithms for a maritime engagement missile program. Algorithms designed to run real-time on the missile on-board processor. Served as the computational geometry and perspective projection SME. Designed and optimized all algorithms for running real-time on mission control unit

Obstacle Detection Algorithm: Developed real-time algorithm for detecting potential obstructions during flight without any a priori knowledge of size, shape, or spectral response. Algorithm detects and finds extents of objects using statistical analysis, grayscale morphology, projective geometry, and clustering logic.

Wireframe Rendering Algorithm: Developed real-time rendering algorithm for projection and hidden line removal of wireframe models. Algorithm pre-calculates much of the model at design time and uses a highly optimized fragmentation and raytrace technique for real-time portion of algorithm. Speed increase over existing projection algorithm was ~3-4 orders of magnitude.

Tool Development: Designed and built wireframe viewing/modification tools, data reduction tools for mission analysis, data truthing tools, and 6DOF models.

Algorithm Optimization: Redesigned core functions used throughout image processing algorithms to increase speed. Improvements ranged from 3x to 100x for: binary/grayscale morphological operators, symmetric convolution, convex hulling, Sobel operator, boxsum, etc.

Position Title: Systems Engineer Staff
Organization:
Missiles and Fire Control (MFC)
Strike Weapons
Joint Air to Surface Standoff Missile (JASSM)
Precision Tageting Module (PTM)
Responsibilities:

Worked as an algorithm and software developer for missile mission planning software.  Served as satellite imagery SME for the group and was technical liaison with government customer, NGA, and other LM divisions.  Designed and implemented several large-scale tools for the program, including:

Boolean Tool Suite: Created a geometric Boolean tool suite to union, intersect, difference, and subtract surfaces and volumetric objects. 

N-Side Pitched Roof Building Extractor: Tool deciphered shape of complex pitched roof buildings by analyzing the footprint of the building and roof structure.  Built a solid object representing the full building from primitive pieces using geometric Boolean operations.

Mensuration Recalculation: Designed algorithm to resample satellite imagery and calculate new rational polynomial coefficients for mensuration to support mission planning requirements. 

Linear Approximation of Pushbroom Display: Designed algorithm to calculate a 4x4 camera quad to approximate the non-linear appearance of pushbroom satellite imagery for OpenGL display.  Transform included spatial transforms for coordinate system orientation and shear, horz and vert translation, and rotations.)
