Abstract: The present disclosure relates to an assistance device for image recognition that comprises a memory storing sets of image descriptors, respectively associated with an image area and including first vector data, second angle data, and third scale data. A first operator receives a designation of two descriptors and establishes a Boolean representing a check of a similarity criterion of the descriptor vectors from a comparison among first data. A second operator receives a designation of two descriptors and establishes a rotation angle parameter from the second data. A third operator receives a designation of two descriptors and establishes a scale factor parameter from the third data.
