It is known that a tree convex network is globally consistent if it is path consistent. However, if a tree convex network is not path consistent, enforcing path consistency on it may not make it globally consistent. In this paper, we investigate the properties of some tree convex constraints under intersection and composition. As a result, we identify a sub-class of tree convex networks that ar...

Research on the interpretation of image flow (or optical flow) until now has mainly focused on instantaneous flow fields. This limits the scope of the problems that one can address and the accuracy of the results. Here we extend a previous formulation of the problem to incorporate temporal variation of image flow. We illustrate our approach by solving specific cases which are of practical signi...

This paper presents a practical system for vision-based traffic scene analysis from a moving vehicle based on a cognitive feedback loop which integrates real-time geometry estimation with appearance-based object detection. We demonstrate how those two components can benefit from each other’s continuous input and how the transferred knowledge can be used to improve scene analysis. Thus, scene in...

Suggestions that the internet has facilitated existing trends towards the increasing disconnection of individuals from substantive communities have been balanced by a variety of empirical case-studies demonstrating evidence of significant communal features on some online discussion forums. While recognising the role of discussion forums in facilitating community, this paper seeks to shift the f...

Spend your few moment to read a book even only few pages. Reading book is not obligation and force for everybody. When you don't want to read, you can get punishment from the publisher. Read a book becomes a choice of your different characteristics. Many people with reading habit will always be enjoyable to read, or on the contrary. For some reasons, this natural image statistics a probabilisti...
