finding head pose looking direction

[SaddamBInSyed]

@lincolnhard thanks for your work.

I am using the below code to find the head pose looing direction. (left, right, top, bottom)

y_value = float(str("{:7.2f}".format(euler_angle[1, 0])))
               x_value = float(str("{:7.2f}".format(euler_angle[0, 0])))
               if y_value >= 20:
                   print("looking left")
               elif y_value <= -20:
                   print("looking right")

               if x_value >= 20:
                   print("looking down")
               elif x_value <= -20:
                   print("looking up")

and seems it is fine.

if anyone knows better formula please share here.
