Automatic Video Pause Detection Filter

Increasing interest in multimedia research has been drawn upon the development of video indexing and content-based image retrieval techniques. In this report, we proposed several pause detection algorithms, which instead of searching for signi cant visual transitions, the algorithms detect signi cant pauses in video streams. A realization of the algorithmswas implemented using ImageTcl toolkit ...

The Extended Kalman Filter Applied to a Feed - Forward Neural

| This paper describes a feedforward neural network architecture trained with the extended Kalman lter algorithm instead of the standard (LMS) method. It presents a simpliied recursive procedure for calculating the necessary derivatives. The resulting algorithm is then used to train a network to adapt to the decision boundary of an optimal receiver for a binary communication channel, resulting ...

Ancient whales did not filter feed with their teeth

The origin of baleen whales (Mysticeti), the largest animals on Earth, is closely tied to their signature filter-feeding strategy. Unlike their modern relatives, archaic whales possessed a well-developed, heterodont adult dentition. How these teeth were used, and what role their function and subsequent loss played in the emergence of filter feeding, is an enduring mystery. In particular, it has...

The Feed-Forward Chain as a Filter-Amplifier Motif

Husdpeth, Magnasco, and collaborators have suggested that the auditory system works by tuning a collection of hair cells near Hopf bifurcation, but each with a different frequency. An incoming sound signal to the cochlea then resonates most strongly with one of these hair cells, which then informs the auditory neuronal system of the frequency of the incoming signal. In this paper we discuss two...
