The trace of the gradient matrix, (Ix)^2 IxIy IxIy (Iy)^2 is invariant to feature orientation The input can be either an image pyramid or a base image In the latter case a pyramid is generated as input to the scale max response search. The interval between scales is uniform on according to the logarithm of scale ratios. For example if the scale range is from 1 to 8 and the scale ratio is sqrt(2), the scale intervals are: 1, 1.4, 2, 2.8, 4, 5.6, 8, i.e., 8/4 = 2, 2^(0.5) = 1.4, 4*1.4 = 5.6
