主 题:Bayes network scene understanding object frame probabilistic model
摘 要:In this paper,we propose a probabilistic scene model using object frames,each of which is a group of co-occurring objects with fixed spatial *** contrast to standard co-occurrence models,which mostly explore the pairwise co-existence of objects,the proposed model captures the spatial relationship among groups of *** information is closely tied to the semantics of the underlying scenes,which allows us to perform object detection and scene recognition in a unified *** proposed probabilistic model has two major *** first models the dependencies between object frames and objects by adopting the Latent Dirichlet Allocation model for text *** second component characterizes the dependencies between object frames and scenes by establishing a mapping between global image features and object frame *** results show that the induced object frames are both semantically meaningful and spatially *** addition,our model significantly improves the performance of object recognition and scene retrieval.
