METHOD FOR TRANSFORMATION OF IMAGE DESCRIPTOR BASED ON GRADIENT HISTOGRAM AND RELATIVE IMAGE PROCESSING APPARATUS

摘要

To provide a method for transformation of an image descriptor based on a gradient histogram and a relative image processing apparatus.SOLUTION: A method for transforming an image descriptor H, based on a gradient histogram hhaving a plurality of histogram bins h, into a transformed gradient histogram descriptor V including a set of values vcomprises the step of applying at least one criterion for calculating the set of values v, where the at least one criterion has a location criterion of the histogram bins h.SELECTED DRAWING: Figure 8
