Dans cet étude, nous nous concentrons sur l'analyse et l'indexation automatique des séquences vidéo. Cela permet une récupération et un accès efficace aux données. Les vidéos étant généralement stockées et transmises sous forme encodées, notre approche se base sur l'analyse dans le domaine compressé. Ce domaine présente un compromis raisonnable entre cout de calcul et qualité des résultats. Les informations les plus pertinentes encodées dans le flux H.264 sont les vecteurs de mouvement (VM). Ces vecteurs sont associés aux macroblocs dans les images prédites (de type B et P). Nous présentons diverses techniques non-supervisés pour déterminer le mouvement de la caméra, détecter et suivre les objets en mouvement dans les vidéos. Ces analyses s...
