# NAME       TYPE   DEFAULT MEANING
# ---------------------------------------------------------------------------------------------
# img_in1    Matrix ---     First input image
# img_in2    Matrix ---     Second input image
# weight     Double ---     The weight given to the second image.
#                           0 means only img_in1, 1 means only img_in2 will be visible
