The multicast admission control and routing problem can be defined as follows: network users issue online requests for connections to various multicast sources. The network either accepts a request or rejects it (the admission control decision). If the request is accepted, a path with sufficient bandwidth is established from the requesting user either to(More)
Modern Color Filter Array (CFA) designs avoid overlap of luminance and chrominance spectra as it is widely believed to cause irreversible crosstalk and aliasing. In this paper, we present a simple formulation of the demosaicking problem that disregards spectral overlap - and thus the geometry of the spectra - and instead connects the luminance and(More)
We show that a recently developed universal demosaicker by the present authors greatly outperforms existing demosaickers when tested with a realistic optical pipeline. We present speed and quality optimizations of this demosaicker for the case of regular pattern color filter arrays. We implement and extensively test optimized versions for several common(More)
The Online Maximal Dense Tree problem is as follows: given a weighted directed graph and a source node, users issue online requests for connection to the source node. A request can either be accepted or rejected (the admission control decision). If the connection request is accepted, it must be connected to the source or to a node previously connected to(More)
Chromatic Aberration of lenses is becoming increasingly visible with the rise of sensor resolution, and methods to algorithmically correct it are becoming increasingly common in commercial systems. A popular class of algorithms undo the geometric distortions after demosaicking. Since most demosaickers require high frequency correlation of primary colors to(More)
We present CFA designs that faithfully capture images with specified luminance and chrominance bandwidths. Previous academic research has mostly been concerned with maximizing PSNR of reconstructed images without specific regard to chrominance bandwidth and cross-talk. Commercial systems, on the other hand, pay close attention to both these parameters as(More)
Miltefosine, the only oral drug for visceral leishmaniasis (VL), is being used as the first-line drug under the VL elimination program in the Indian subcontinent. Miltefosine is an oral drug which was used as a topical application for skin metastasis of breast cancer. It was found to be effective against Leishmania donovani The main adverse events (AE)(More)
