Image Processing Software


Scion Corporation [12] provides a free download of Scion Image Beta 4.02 for Windows Acquisition and Analysis Software, a windows version of NIH Image Software [13], a public domain image processing and analysis program for the Macintosh developed by the Research Services Branch (RSB) of the National Institute of Mental Health. Scion Image allows TIFF files to be imported and manipulated in all the ways necessary in this experiment. Multiple images can be added, subtracted, multiplied, and divided by one another or by a constant value. The intensity values of individual pixels can be determined, and an adjustable scale of false-coloring can group pixels of the same intensity value by color. A histogram can be created for the image in its entirety, graphing the amount of pixels of each value present in the file. A profile can also be made of a single straight line of pixels, showing their relative values in a graph. In short, the software is capable of every function required by the rubrics of Hielscher etal, [1] and Yao etal, [14] for the creation of a full 4x4 Mueller matrix.

The Scion software was installed and run in the same donated Pentium-1/166 computer used to operate the camera.
