Abstract
Método para codificar un descriptor de imágenes (H) en base a un histograma de gradientes (hₚ) en un descriptor transformado (V) que comprende subdescriptores transformados (vₚ), donde cada histograma de gradientes (hₚ) comprende una pluralidad de sectores de histograma (hⁱ) y cada subdescriptor (vₚ) comprende un conjunto de valores (vʲ), caracterizado en que dichos subdescriptores (vₚ) se generan de acuerdo con una lista de orden de utilización de elementos que especifica un índice de subdescriptores (p) de dicho conjunto de subdescriptores (vₚ) y un índice de elementos (j) de dicho conjunto de valores (vʲ).
