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 -
