Hi,
I want to differentiate between signals that follow more or less same route. However, when plotting the signals you can tell there are differences. An example of four signals is found below. I am looking for parameters that will quantitatively make a distinction between the signals. Some examples include: -Area, -Perimeter, -Roundness (using isoperimetric inequality), -Transforming to polar coordinates or frequency and checking result,...
That's basically what I can think of for now. Maybe you have another suggestion for what I can use?
