i need coding for automatic car counting for unmanned aerial vehicle images

automatic car counting method which it consist of following steps

1. screening
2. keypoint extraction
3. keypoint classification
4. keypoint merging.

screening is performed to isolate the road tracking cars. keypoints extraction is done using SIFT transforms. keypoint classification is done for discriminating cars and other. keypoint merging is done to count the number of cars using an merging algorithm.
