Color Transformation to HSI

[Eva Heintz]

I'm new to Image J & I am trying to transform a color image into HSI. The
output looks different than an image/aquisition program, Metamorph, that I
was using. Looks like the Intensity image is actually the Hue or
Saturation image. Any suggestions?

Hi Eva,

We need more detail to help. What exact commands or plugins did you use? What versions of ImageJ and any plugins?
My ImageJ has commands for RGB to HSB, not HSI. (E.g.: menu command Image->Type->HSB Stack)

Part of the problem may be that these color models are not well standardized.  See for example the article at
http://en.wikipedia.org/wiki/HSI_color_space
So Metamorph may be using a different definition of HSI than the ImageJ plugin.
