Ok I need to understand how some harmonic calculations work to apply some transforms.
If I have a periodic functiion f(x). And I have the values of that function for several values of x (say x goes from 0 to 359) so I have
f(0)=3 f(1)=5 ... etc
So if I'm asked to take the max of those values without the first harmonic. How can I do this? and what does it mean?
Edit: Here is the pdf of the method I'm implementing, it's the only one I found publicaly available. There are tables of functionals on the paper which are applioed to texture analysis of images. The result of the second set of functionals is a periodic function and on the third set of functionales there are a couple of functionales where you need to get i of xi so that xi is the max or min value without the first harmonic. http://pdf.aminer.org/000/067/295/texture_classification_with_thousands_of_features.pdf
