Abstract:
1. An assistance device for image recognition, comprising: a memory configured for storing a plurality of sets of descriptors, each set corresponding to an image, each descriptor being associated with a designated area of the image, and comprising first data of the vector type characteristic of said designated area of the image, second data of the angle type characteristic of said designated area of the image, and third data of the scalar type characteristic of said designated area of the image, a first operator configured for receiving a designation of two descriptors and of establishing a Boolean variable reflecting a verification of a similarity criterion of the descriptor vectors, from a comparison between the first data of these descriptors, a second operator configured for receiving a designation of two descriptors and of establishing a rotation angle parameter from the second respective data of both descriptors, a third operator configured for receiving a designation of two descriptors and of establishing a scale factor parameter from the third data of these descriptors, a controller configured for receiving the designations of a first set of descriptors corresponding to a first image and of a second set of descriptors corresponding to a second image, and laid out so as to apply the first operator to each pair formed by a descriptor of the first set, and by a descriptor of the second set, in order to infer therefrom a list of pairs of similar descriptors, calling the second operator and the third operator for each of the pairs of descriptors of said list and storing in memory the whole of the obtained parameters, and an estimator of the likeness between the images respectively corresponding to the first and to the second set of descriptors, from statistical processing on said set of parameters.
