Computer Vision Programmer/Roboticist

September 2012-Current
applied minds
Submitted several changes to ROS Point Grey camera driver upstream to fit AMI use cases.
Changed OpenCV CUDA stereo algorithm to reduce latency by allowing multiple concurrent uses in single process.
Generate point cloud data of environment from stereo cameras.
Used point clouds to build map of local environment for modeling traversability of environment.
Applied various scoring methods to select "interesting" sections of video.
Modeled reception of sound sources at microphones to improve signal quality when using multiple microphones.
Terrain classification via Gaussian Mixture model.
Fused several different methods of estimating position to get stabler and more accurate estimates, including accelerometer and gyroscopic data with two visual odometry systems.
