Jim H. Chandler, Tom Buffin-Belanger, Steve Rice, Ian Reid, David J. Graham
2003 Photogrammetric Record  
Imagery of both the original streambed and the cast facsimile was acquired using a non-metric Kodak DCS460 digital camera and digital elevation models and orthophotographs were derived and compared to  ...  Digital photogrammetry has been used to develop and test an artificial river bed moulding and casting system, which allows the pebbles within a coarse grain river bed to be recreated for hydraulic research  ...  A useful method that can be adopted to rapidly identify differences in orthophotographs graphically, is to generate an animation.  ...

Digital color imaging

G. Sharma, H.J. Trussell
1997 IEEE Transactions on Image Processing  
Present-day color recording and reproduction systems are reviewed along with the common mathematical models used for representing these devices.  ...  In order to establish the background and lay down terminology, fundamental concepts of color perception and measurement are first presented us-ing vector-space notation and terminology.  ...  As many as fifteen distinct physical mechanisms have been identified that are responsible for color in nature [114] .  ...

The Philosophy of PCM

B.M. Oliver, J.R. Pierce, C.E. Shannon
1948 Proceedings of the IRE  
Oversampling in conjunction with quantization noise shaping and digital filtering are the key concepts in sigma-delta converters, although oversampling can be used with any ADC architecture.  ...  If digital filtering is used to filter out noise components outside the bandwidth BW, then a correction factor (called process gain) must be included in the equation to account for the resulting increase  ...  ACKNOWLEDGEMENT The author would like to thank Dan Sheingold of Analog Devices for the permission to use material directly from his classic 1986 Analog-Digital Conversion Handbook (Reference 3).  ...

Consciousness in Neural Networks?

Edmund T Rolls
1997 Neural Networks  
The resulting lifetime of a bubble depends on the density of the cells in the area supporting it, with the longest lifetime occurring for highest density.  ...  The Alopex procedure changes all pixel intensities on the CRT before each successive presentation depending on the correlation (or anticorrelation) between the preceding changes in pixel intensity and  ...  Clarion indeed uses implicit learning to develop tacit (implicit) representations in the bottom level and thus acquires intuition in the sense identified above.  ...
