^ Name ^ Detector ^ Descriptor ^ Invariance ^ Pros and cons ^
^ Harris | points with high gradient in two orthogonal directions | The two eigenvalues, but very weak | Rotation, scale somewhat, intensity | |
^ FAST | points with enough consecutive pixels on a circle around them that are brighter of darker than them | - | Rotation | faster but less robust than harris |
^ SIFT | | | | |
^ SURF | | | | |
^ BRIEF | - | set of binary comparisons of intensity between pairs of pixels on a smoothed patch | - |
