Blob Detection - The Hybrid Laplacian and Determinant of The Hessian Operator (Hessian-Laplace)

The Hybrid Laplacian and Determinant of The Hessian Operator (Hessian-Laplace)

A hybrid operator between the Laplacian and the determinant of the Hessian blob detectors has also been proposed, where spatial selection is done by the determinant of the Hessian and scale selection is performed with the scale-normalized Laplacian (Mikolajczyk and Schmid 2004):

This operator has been used for image matching, object recognition as well as texture analysis.
