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

Abstract: A method for encoding an image descriptor (H) based on gradient histograms (hp) into a transformed descriptor (V) having transformed subdescriptors (vp), wherein each gradient histogram (hp) includes a plurality of histogram bins (hi) and each subdescriptor (vp) includes a set of values (vj), wherein the subdescriptors (vp) are generated according to an element utilization order list specifying a subdescriptor index (p) of the set of sub descriptors (vp) and an element index (j) of the set of values (vj).
