2014-02-17 21:46:22 -0600 | asked a question | Tutorials for Beginner Cascade Classifier Training in C++? I am a fifth-year University art student and hobbyist programmer. I am fairly familiar with C++ and have managed to familiarize myself with OpenCV thanks to the abundance of fine resources. I am working on an ongoing project that will culminate in a museum installation. So far I have created a program that tracks movement in live webcam video stream. The program can track many different objects by using absdiff comparisons on image frames, creating a threshold image, and analyzing the contours. I am using variables for threshold sensitivity and blur amount to somewhat control contour sizes. I have provided my source code at the bottom of this post. The problem I have, is that a single person or object may be treated/tracked as many different objects based on lighting and other factors. I am interested in Cascade Classifier Training in order to identify the human figure. The background of my live stream is simple, monochromatic, static, and well-lit - so I don't imagine it will be hard to create negative training examples. The position of the camera will be unchanging, so I should be able to use it to take many still images of human figures throughout the space, for use as positive training examples. I hope my understanding of Cascade Classifier Training is somewhat accurate. I am seeking simple beginner tutorials to instruct me step-by-step in training a classifier, with example code. Any help or resources that you can provide are of great help and interest, and I thank you in advance. I am also interested in attempting to map the detected movement to a drawn space: although I am tracking the X & Y coordinates of the center of the contour objects, I have no way to, say, map the human figure's movement to a very basic rendered figure. This thread is likely not the place for this question, but perhaps someone looking at my cascade question can point me in the right direction. Thing.h Thing.cpp main.cpp (more) |
