##Object Tracking Project Use C++ with OpenCV and cvBlob to perform image processing and object tracking, using a webcam. Originally, built to test Raspberry Pi performance.
Original code for my blog post, 'Object Tracking on the Raspberry Pi with C++, OpenCV, and cvBlob'
Changes to original project branch:
- Refactored video blob tracking methods into a separate class.
- Refactored hard-coded color ranges. Now input parameters.
- All methods now accept common struct containing input parameters.
- New window displays low and high RGB color range color sample.
- Added support for Travis-CI. Project now building on each commit to GitHub.
- Project contains bash commands/script to install latest OpenCV, cvBlob, and all necessary dependencies on Ubuntu.
- Project contains bash commands/script to git clone, build, package, and run this project on Ubuntu.
- All installation and configuration tested with fresh Ubuntu image on VirtualBox VM
