Average Color Tool Results - HSI
Hue, Saturation, and Intensity (HSI) is a representation of color space that is closer to human perception of color
dynamics.
The results are shown as an average for each value: hue, saturation, and intensity. In addition, the standard deviation
is displayed so that you can test the variance of color. The greater the range of colors of the pixels within the ROI, the
higher the standard deviation will be. If all pixels are uniformly the same color, the standard deviation will be zero.
