CVA, the Calculator of Vision of Anything, can predict what any light source or any colored surface under any kind of illumination would look like to any person or animal.

Also does all optical films and CCDs.

This is one of several new software applications available at www.eknent.com/software .

CVA is a very feature-rich software application. Its function is to process light spectra - from the UVB to well into the Photographic Infrared - and display the resulting colors the way various vision systems see them. Even processes entire photographs through its companion application, MIF Editor, using CVA's Multiband Image Format, which allows images to contain up to 256 wavelength bands - from the soft X-ray region to the thermal infrared.

With CVA, you can see any piece of the world through the eyes of the creatures that live there. You can see paintings and other kinds of artwork through the eyes of a colorblind person. You can simulate taking pictures with theoretical color films and color cameras that have not yet even been prototyped. You can test designs for multiband cameras, comparing films and filters to find the optimum combinations for your purposes. The applications are endless!

Here is a demonstration of CVA's "scene-viewing" functionality. We photographed a lake scene with a CCD and some inexpensive filters, taking three visible bands (red, green, blue), an infrared band, and a UV band. Here it is through the eyes of some of the animals that live in the vicinity:

CVA will even show you the exact color of any point on the image. Simply slide your mouse pointer over it, and a set of numbers representing color intensities will indicate the perception of that point on the image. CVA actually calculates the colors and images per receptor cell, extrapolating each retina cell's individual response to a color or scene. This is because animals that "only see blue and yellow", such as cats, dogs, horses, and white-tailed deer, really have different cone sensitivities and therefore see colors differently. CVA takes advantage of these differences, simulating each unique vision system as accurately as possible.

MIF Editor is great for a lot of applications: visual research, astronomy, remote sensing/surveying, storing satellite images, and much much more. Its 256-band capability ensures that it can handle anything you can photograph. Its theoretical limit of resolution is 32,767 by 32,767 - well beyond the resolution of any commercially available camera - and it can handle any wavelength from 1 to 32,767 nanometers (.001 to 32.7 microns). Here is an example of what MIF Edtor can do:
