查询词典 integral invariant

Phase congruency is a dimensionless quantity that is invariant to changes in image brightness or contrast.By the integral projection of the phase congruency image as features and the support vector machines as the classifier,The paper has been robust to various illumination and sharply accelerated via coarse filtration.
