A New Video Compression Scheme Combining Conditional Replenishment and Address Event Representation
A novel video compression scheme is presented in this paper. This algorithm is implemented based on a conditional replenishment Address Event Representation (AER) imager, where im...

Dynamic Wavelength Sharing Policies for Absolute QoS in OBS Networks
— We consider the problem of providing absolute QoS guarantees to multiple classes of users of an OBS network in terms of the end-to-end burst loss. We employ Markov decision pro...

On Choosing Wavelet Resolution in Image Deblurring
In wavelet deblurring of noisy images the finest resolution levels are key parameters which require fine tuning. In this paper we present a blockwise thresholding rule in the Fo...
