Detection

Hessian-based interest point localization

Lxx(x,y,σ) is the Laplacian of Gaussian of the image

It is the convolution of the Gaussian second order derivative with the image

Lindeberg showed Gaussian function is optimal for scale-space analysis

This paper argues that Gaussian is overrated since the property that no new structures can appear while going to lower resolution is not proven in 2D case
