Corner Detection Using Laplacian of Gaussian Operator

This paper describes a fast corner detection algorithm making use of the Laplacian of Gaussian operator. We propose a general corner model and analyze its behavior in scale space. The study shows that the response of the operator has a stable elliptic extremum which always lies inside the corner. Using a multi-scale representation limited to two scales and the sole laplacian of Gaussian operator, we build an accurate corner detector with low cost. Promising experimental results show the eeciency of the detector.
