... Previous: Background Fluctuation Analysis from the Multiscale Entropy . ... A new measure of information is defined which is based on noise modeling and incorporates resolution scale. Properties of this measure are discussed. ... Additionally it allows for image noise modeling, and subsequent noise removal. ... Hence information- and entropy-based processing technologies will be necessary for the effective design and implementation of large, future generation, image databases. ...

This directory contains prototypes for scripts that may be called by the camera driver. ... The script set_camera_filter should take a filter number as an argument and send a command to a filter wheel. The SBIG filter wheel is supported internally and does not use this script. If you have another filter wheel, then a script such as this would allow you to use XmCCD to control the filter wheel. ... Simply "make" the routine in the ifw directory, and then "make install". ...

The computed band passes. ... The interim correlator input is filtered by 8 analog filters (50 Mhz wide at the 260 Mhz IF... one for each sub correlator). ... For bandwidths of 25 Mhz and below the real data stream is digitally down converted to complex samples I, Q streams. ... The Top figure is the halfband filter bandpass computed from the filter coefficients. ... The computed filter has aliased power, extra IQ filtering, and two applications of the filter on the resulting real bandpass. ...
