Title (EN) EFFICIENT CODING OF PROBABILITY DISTRIBUTIONS FOR IMAGE FEATURE DESCRIPTORS
(FR) CODAGE EFFICACE DE DISTRIBUTIONS DE PROBABILITÉ POUR DES DESCRIPTEURS DE CARACTÉRISTIQUE D'IMAGE
Abstract: front page image
(EN)A method for encoding or compressing probability distributions is disclosed. A first mapping of probability distribution of samples to the types from the predefined set of types is generated. A second mapping of the types in the predefined set of types to lexicographic indexes from the index space is generated. A probability distribution is quantized as a type from the predefined set of types. The type is then mapped to a lexicographic index from the index space that spans the predefined set of types. A code for the lexicographic index is then transmitted and / or stored as part of a feature descriptor.
(FR)L'invention porte sur un procédé de codage ou de compression de distributions de probabilité. Un premier mappage de distribution de probabilité d'échantillons sur les types de l'ensemble prédéfini de types est généré. Un second mappage des types dans l'ensemble prédéfini de types sur des indices lexicographiques de l'espace d'indice est généré. Une distribution de probabilité est quantifiée en tant que type à partir de l'ensemble prédéfini de types. Le type est ensuite mappé à un indice lexicographique à partir de l'espace d'indice qui s'étend sur l'ensemble prédéfini de types. Un code pour l'indice lexicographique est ensuite transmis et/ou stocké en tant que partie d'un descripteur de caractéristique.
