Hi everyone,
I am doing some analyses of tissue color of corals that I took with an underwater camera. I am trying to see if there are differences in tissue color among colonies. My idea is to use the color histograms of the selected colonies. In each image, I have a color standard card, placed next to the coral colony. One of the reasons why we include this card is because red light is attenuated with depth, so objects and images appear more blue the deeper you are, and the coral colonies are all at different depths. We know the RBG values of the color on the card. I am wondering if anyone has experience or advice on how I could use this color standard card in ImageJ to perform a sort of correction before using color histograms?
Many thanks,
KL
