Rain on Our Parade

The planned flight for today had to be delayed because of rain, so no sample imagery will be available until this weekend.  One of our goals is to determine the color of targets.  Since this project is under the assumption that targets will be reasonably segmented (we can expect some noisy brush or grass in the background), one approach we are going to try as soon as we have imagery is to use color histograms to figure out the colors.

Targets are two colors, the majority of which is the background color.  The alphanumeric makes up only a small portion of any given color, so we can expect the distribution of color to have its highest peak in the background color, followed by the alphanumeric.  We will have to check this theory once we have actual images.
