flow = obj.calc(I0, I1)
flow = obj.calc(I0, I1, 'OptionName',optionValue, ...)

Input

• I0 first 8-bit single-channel input image.
• I1 second input image of the same size and the same type as I0.

Output

• flow computed flow image that has the same size as I0 and type single (2-channels).

Options

• InitialFlow specify the initial flow. Not set by default.
