MPEG-4 AVC stream-based saliency detection: application to robust watermarking

Autor: Mihai Mitrea, Patrick Le Callet, Marwen Hasnaoui, Marwa Ammar

Publikováno v: Signal Processing: Image Communication
Signal Processing: Image Communication, Elsevier, 2018, 60, pp.116-130. ⟨10.1016/j.image.2017.09.007⟩

International audience; By bridging uncompressed-domain saliency detection and MPEG-4 AVC compression principles, the present paper advances a methodological framework for extracting the saliency maps directly from the stream syntax elements. In this

Visual saliency extraction from compressed streams

Autor: Ammar, Marwa

Les fondements théoriques pour la saillance visuelle ont été dressés, il y a 35 ans, par Treisman qui a proposé "feature-integration theory" pour le système visuel humain: dans n’importe quel contenu visuel, certaines régions sont saillantes

International audience; A saliency map provides information about the regions inside some visual content (image, video, ...) at which a human observer will spontaneously look at. For saliency maps computation, current research studies consider the un
