Abstract
A method of processing an image including pixels distributed in cells and in blocks is disclosed, the method including the steps of: a) for each cell, generating n first intensity values of gradients having different orientations, each first value being a weighted sum of the values of the pixels of the cell; b) for each cell, determining a main gradient orientation of the cell and a second value representative of the intensity of the gradient in the main orientation; c) for each block, generating a descriptor of n values respectively corresponding, for each of the n gradient orientations, to the sum of the second values of the cells of the block having the gradient orientation considered as the main gradient orientation.
