Conclusion

This chapter has introduced the common methods of feature detection:

• cross-correlation for detecting perfectly known patterns;

• Canny detector for detecting lines (based on the image gradient);

• Harris detector for detecting corners (based on the intensity variations in the pixel neighborhood);

• Hough transform for detecting lines or circles (by transforming the image into a parameter space).
