bridge rectifier circuit that shows how out-of-phase the current is with respect to voltage

Active contours or snakes" can be used to segment objects automatically. The basic idea is the evolution of a curve, or curves subject to constraints from the input data. The curve should evolve until its boundary segments the object of interest. This framework has been used successfully by Kass

The function takes three input arguments (function and two initial guesses belonging to the interval). After iterations, it returns the root of the function. The fourth input argument is to change the stopping criteria of the loop.
