This paper proposes to improve our previous work on the concept-based video shot indexing, by considering an ontological concept construction in the TRECVid 2007 video retrieval, based on two steps. First, each single concept is modeled independently. Second, an ontology-based concept is introduced via the representation of the influence relations between concepts and the ontological readjustment...
This paper proposes to compare three hybrid concept similarity measures for video shots indexing and retrieval [1], based on two steps. First, individuals concepts are modeled independently. Second, an ontology is introduced via the representation of the relationship between concepts and the ontological readjustment of the confidence values. Our contribution lies in the manner in which inter-concepts...
This paper presents an automatic semantic concept extraction method which employs low level visual feature fusion. Both static and dynamic feature fusion approaches are studied and evaluated. The main contributions of this paper are: a novel dynamic feature fusion approach inspired from coding is proposed to create compact yet rich signatures; Statistical study of descriptors with and without fusion...
This paper proposes an automatic semantic video content indexing and retrieval system based on fusing various low level visual and shape descriptors. Extracted features from region and sub-image blocks segmentation of video shots key-frames are described via IVSM signature (Image Vector Space Model) in order to have a compact and efficient description of the content. Static feature fusion based on...
