Abstract:
It is described a method for transforming an image descriptor, based on a gradient histogram (h) comprising a plurality of histogram bins ( h i), into a transformed gradient histogram descriptor (v) comprising a set of values ( v j), wherein it is provided the step of applying at least one criterium for calculating said set of values ( v j), said at least one criterium comprising a location criterium of said histogram bins ( h i). The invention also relates to an image processing device suitable for carrying out the method.
