image domain, a multi-scale approach is therefore necessary. In (Lindeberg 2013b, 2015) 2 3 it is shown that the determinant of the Hessian operator performs significantly better than the Laplacian operator or its difference-of-Gaussians approximation, as well as better than the Harris or Harris-Laplace operators, for image-based matching using local sift-like or surf-like.

Thus, simultaneous selection of interest points (x,y)displaystyle (hat x,hat y) and scales tdisplaystyle hat t is performed according to (hat x,hat y;hat t)operatorname argmaxminlocal x,y;t nabla _norm2L x,y;t). Laplacian of the, gaussian (LoG). Using a mixture of the above: Combining several good approaches normally yields an even better result. Here is a list of the most common techniques in face detection: (you really should read to the end, else you will miss the most important developments! Beyond local contrast and extent, these scale-space blobs also measured how stable image structures are in scale-space, by measuring their scale-space lifetime.
