Detailed Description

An implementation modelling the centre-surround response, used for construction of spatial uniqueness maps.

Based on the difference-of-Gaussians pyramid approach of Itti. A single Gaussian pyramid is created. Neighbouring pyramid entries are subtracted (eg Pyramid level 0 - Pyramid level 1, 1-2, 2-3 ...etc), and so are 2nd neighbours (eg 1-3,2-4,3-5..etc), to obtain spatial uniqueness at various spatial scales. All resultant subtraction results (the difference of Gaussian maps) are summated to yield the centre-surround map output.
