image – single-channel 8-bit input image.
threshold1 – first threshold for the hysteresis procedure.
threshold2 – second threshold for the hysteresis procedure.
apertureSize – aperture size for the Sobel() operator.
L2gradient – a flag, indicating whether a more accurate L_2 norm =\sqrt{(dI/dx)^2 + (dI/dy)^2} should be used to calculate the image gradient magnitude ( L2gradient=true ), or whether the default L_1 norm =|dI/dx|+|dI/dy| is enough ( L2gradient=false ).
