Effective Codebooks for Human Action Representation and Classification in Unconstrained Videos

“Effective Codebooks for Human Action Representation and Classification in Unconstrained Videos” by L. Ballan,  M. Bertini,  A. Del Bimbo,  L. Seidenari and G. Serra has been accepted for publication in the IEEE Transactions on Multimedia.

Recognition and classification of human actions for annotation of unconstrained video sequences has proven to be challenging because of the variations in the environment, appearance of actors, modalities in which the same action is performed by different persons, speed and duration and points of view from which the event is observed. This variability reflects in the difficulty of defining effective descriptors and deriving appropriate and effective codebooks for action categorization. In
this paper we propose a novel and effective solution to classify human actions in unconstrained videos. It improves on previous contributions through the definition of a novel local descriptor
that uses image gradient and optic flow to respectively model the appearance and motion of human actions at interest point regions. In the formation of the codebook we employ radiusbased clustering with soft assignment in order to create a rich vocabulary that may account for the high variability of human actions. We show that our solution scores very good performance with no need of parameter tuning. We also show that a strong reduction of computation time can be obtained by applying codebook size reduction with Deep Belief Networks with little loss of accuracy.

Moody's Downgrades Italian Banks

Moody's Downgrades Italian Banks

Moody's Investors Service kicked off its long-awaited downgrades of European and global banks by docking the credit ratings of 26 Italian lenders, a move that could ratchet up the continent's banking woes at a critical time for the currency union.
The downgrades, which cite the banks' vulnerability to mounting loan defaults and potential funding problems, were expected, but they nonetheless add to concerns by making it more expensive for the banks to finance themselves via the capital markets.
The ratings for Italian banks are now among the lowest within advanced European countries, reflecting these banks' susceptibility to the adverse operating.

This is my response to a question I read elsewhere about the possibility of American media being dishonest/misleading or would
they /could they ever feed us propaganda or censor vital news in a modern technological age, where communication over great distances is nearly instant and video cameras are everywhere.. I
Well to answer that question, the fact is that the mainstream media here today is PRIMARILY fed propaganda and distraction. It has been this way for nearly a century.
To understand this thoroughly you must look at this story like most, from the beginning. In 1913 The Federal Reserve Act was passed (google it, the story is insane!). The passing of the (unconstitutional) Federal Reserve Act meant that the US Government will forfeit all rights to coin (or...
