Analyze video grabber frames (or a loaded image) for SURF keypoints. Draw a lasso around the keypoints you would like to use in a detector. Then save object descriptor files. Later, load descriptor files and detect objects in new images.
- Choose an object that generates lots of features. Textures, patterns and text are good candidates for feature detection.
- Circles show the rough size of each detected feature. Gray features are the weakest and white are the strongest. The more good features, the better a detector.
- Draw a polygon around the features you want a detector to use.
- Save the object descriptors to a YML file. After saving, and whenever you load the descriptor file, the detector will try to find your object in the latest frame.
