DESCRIPTION
The current directory contains functions allowing to extract keypoints
also called "feature points", "corners", "interest points", etc.
The following algorithm are provided :
- Harris
- SUSAN
- Harris-Laplace
- Laplacian of Gaussian (LoG)
- Gilles
The input image must be a gray level image. The output is a matrix of
dimension Nx2 or Nx3 with N the number of keypoints extracted. The first
column gives the row poisition of the keypoints and the second column
gives the column position of the keypoints. The third column gives
the feature scale of the keypoints. This scale corresponds to the radius
of the local neighborhood to consider. Note that the SUSAN algorithm is
a contribution of Joaquim Luis.
Run the test function to see an example.
