TLDR
A computational model for analyzing a video shot based on a novel principle of perceptual prominence that captures the key aspects of mise-en-scene required for characterizing a video scene.Abstract:
We present a novel approach for applying perceptual grouping principles to the spatio-temporal domain of video. Our perceptual grouping scheme, applied on blobs, makes use of a specified spatio-temporal coherence model. The grouping scheme identifies the blob cliques or perceptual clusters in the scene. We propose a computational model for analyzing a video shot based on a novel principle of perceptual prominence. The principle of perceptual prominence captures the key aspects of mise-en-scene required for characterizing a video scene.read more

Iterative Tensor Voting for Perceptual Grouping of Ill-Defined Curvilinear Structures
TL;DR: A novel approach is proposed for perceptual grouping and localization of ill-defined curvilinear structures by gradually shifting from an exploratory to an exploitative mode and compared to prior methods on synthetic and annotated real data, showing high precision rates.

Laws of organization in perceptual forms.
TL;DR: Theoretically I might say there were 327 brightnesses and nuances of colour, and do I have "327"? No. It is impossible to achieve "327 " as such.

Probabilistic Reasoning In Expert Systems: Theory and Algorithms
TL;DR: This text is a reprint of the seminal 1989 book Probabilistic Reasoning in Expert systems: Theory and Algorithms, which helped serve to create the field the authors now call Bayesian networks and provides an insightful comparison of the two most prominent approaches to probability.

Structural Saliency: The Detection Of Globally Salient Structures using A Locally Connected Network
A. Sha'asua,Shimon Ullman +1 more
TL;DR: A method for computing saliency by a simple iterative scheme, using a uniform network of locally connected processing elements, to produce a ``saliency map,'''' a representation of the image emphasizing salient locations.
