feature Struct Reference#include <imgfeatures.h>
Detailed DescriptionStructure to represent an affine invariant image feature. The fields x, y, a, b, c represent the affine region around the feature:a(x-u)(x-u) + 2b(x-u)(y-v) + c(y-v)(y-v) = 1 Definition at line 44 of file imgfeatures.h. Member Data Documentation
