total horizontal derivative (THD)
The Total Horizontal Derivative (THD) enhances linear features in a direction perpendicular to the direction of the derivative. It also amplyfies the center of body at it's minimum, and the edges at it's maximum. The THD is calculated bases of the folowing formula:
