This project was the result of a MITACS Accelerate research internship with a partnering company called Klashwerks. The company wanted to have a gesture recognition interface for their mobile device built for the connect car market. During this internship I improved my existing Hand Tracking algorithm by adding hand pose recognition capabilities using HOG Cascade machine learning. Using what I learned with HOG Cascades I then created a robust real-time Hand Gesture Recognition system using HOG Cascades capable of recognizing specific static hand gestures anywhere in a video frame. The system performed well on PC. The Hand Gesture Recognition system was trained with a small sample dataset. I also added an option to the Hand Gesture Recognition system to use HOG SVMs instead of HOG Cascades in order to make speed and performance comparisons with a competing machine learning method. The Hand Gesture Recognition system was attempted to be ported to Klashwerks's mobile device for the connected car market. However the Hand Gesture Recognition system achieved low performance on the mobile device and was replaced with a simpler proximity sensor. This research internship also produced a very large hand gesture image dataset that will be crucial in future research that I do with machine learning methods for my PhD. MITACS Accelerate is a research funding program run by MITACS.

Long Hands Gesture Recognition controller for Halo
Controller for first person video game called Halo. 2015
I made a controller for a first person shooter video game called Halo using my Long Hands Gesture Recognition system. Using two web cameras the system tracks the user's hands. The left hand controls character movement, while the right hand controls aiming and shooting. This served as an important proof of concept that showed that user interfaces capable of rapid response could be made using Long Hands Gesture Recognition.
Long Hands Gesture Recognition System
Contour Shape Analysis and Pixel Colour Based Template Matching for Hybrid Real-Time Gesture Recognition and Tracking. 2015
I integrated my previously developed hand recognition algorithm and my contour based and template based hand tracking algorithms into one system. Unimodal histogram filtering and contour shape analysis works to rapidly detect a hand 5 gesture displayed in the middle of a video frame, and then the two part hand tracking algorithm tracks the hand in subsequent frames. The original contour based tracking algorithm was complemented by adding the template based tracking algorithm. The contour based tracking algorithm partially guides the template based tracking algorithm and this improves the robustness of the template tracking. The template tracking algorithm provides stable tracking of the fingertips improving the system's usability as a user interface input mechanism. The description of the project was drafted as a journal article and a video demonstration was made. My thesis supervisor and I decided to add machine learning to improve the hand gesture recognition and make it position independent before publishing in order to present a more complete system.
Gesture Recognition Paint
Android application allowing a user to draw pictures with hand gestures in front of an Android device camera. 2015
I successfully ported my gesture recognition work to an Android Device. Using my hand recognition and contour based hand tracking algorithms I created an App that lets a user draw on the screen of a tablet by making hand gestures in front of the front facing device camera. The App is called Gesture Recognition Paint. It has 6 different colours to choose from when drawing. This important milestone for my thesis research proved that my gesture recognition methods are scalable to different platforms.
