problem

opencv3.0以及后续版本弃用legacy模块了;

solution

write cv::PatchGenerator module by yourself.

evaluation

=====================================
Evaluation
=====================================
The output of the program is a file called bounding_boxes.txt which contains all the detections made through the video. This file should be compared with the ground truth file to evaluate the performance of the algorithm. This is done using a python script:
python ../datasets/evaluate_vis.py ../datasets/06_car/car.mpg bounding_boxes.txt ../datasets/06_car/gt.txt

result

$python2 ../datasets/evaluate_vis.py ../datasets/06_car/car.mpg bounding_boxes.txt ../datasets/06_car/gt.txt
