This thread is for math questions of any kind. Don’t be embarrassed. I ask silly questions all the time because I am usually forgetful and nonfunctional.
Let’s start with this one. What would you do to prevent
NaNs in log ratios of channels? E.g. I have an arbitrary image that might have values
≤0. Say if I were to do
M=log(G/R). I have to decide the following: Whether and what range to normalize values. Where to place epsilon(s) and what value(s). These considerations will affect the values that end up in
