Digital image-processing activities in remote sensing for earth resources

G. Nagy
1972 Proceedings of the IEEE  
&ion t h a t when two windows do not match, the cumulative d i m c e function rises on the average much more rapidly with earh pair of picture elements examined than when the windows do match [13] .  ...  Once one window function has been adequately matched, the location of the maximum value of the correlation function usually gives a good idea of where the search for the next window function should be  ...  Computer-driven interactive graphic displays together with input devices such as the light pen, the Rand tablet, the Sylvania tablet, the mouse, and joy sticks, have improved man-computer communication  ...

Creating HiRISE digital elevation models for Mars using the open-source Ames Stereo Pipeline

Adam J. Hepburn, Tom Holt, Bryn Hubbard, Felix Ng
2019 Geoscientific Instrumentation Methods and Data Systems Discussions  
Stereogrammetry is a means of producing digital elevation models from stereo pairs of images.  ...  However, only ~ 500 of these pairs have been processed and made publicly available to date.  ...  These, together with a tie-point based multi-resolution image coregistration scheme, guarantee global geo-referencing compliance with HRSC, and by extension 10 MOLA, DEMs.  ...

Viewpoint Dependent Imaging: An Interactive Stereoscopic Display

Scott Fisher, James J. Pearson
1983 Processing and Display of Three-Dimensional Data  
The resultant display is an interactive, lifesize, stereoscopic image that becomes a window into a three dimensional visual environment.  ...  Design and implementation of a Viewpoint Dependent Imaging system is described.  ...  The most extensive examples of perspective imaging are works of art done in the post-renaissance. In most perspective rendered images, there is only one correct viewing position.  ...

Perceptual linearization of video-display monitors for medical image presentation

Bradley M. Hemminger, Richard E. Johnston, Jannick P. Rolland, Keith E. Muller, Yongmin Kim
1994 Medical Imaging 1994: Image Capture, Formatting, and Display  
Based on these analyses we give recommendations for using existing methods when appropriate, and propose new methods or suggest additional work where the current methods fall short.  ...  With the increasing use of video monitors for the display of medical images, we are seeing an increase in the sub-optimal display of images.  ...  SPIE Vol. 2164 /237 Linearization Methods for linearization exist, but they do not attempt to minimize the error in matching the desired luminance values versus the actual ones available on the DAC.  ...
