v.atan2 calculates the angle (in radians) of the vector represented by paired pixels from the two input streams (output as grays float32) v.atan2 calculates the angle (in radians) of the vector represented by paired pixels from the two input streams (output as grays float32) This is quite an accurate calculation and it not as fast as most simple math softVNS 2 processes.
