Retrieves the difference image needed as a temporary storage. Maybe viewed for debugging.
The result is stored in this channel pack.
It is recommended that the image is of type double, as computation of differentials (involving functors) and OpticalFlowWindow use doubles.
| width | - width of the image |
| height | - height of the image |
| max | - expected physical max value (needed if small-integer data used; esp. for subtractions). |
| channels | - provided resource |
Reimplemented from CmdOpticalFlowBase.

inlinevirtual |
Main operation: computes differentials and produces approximation of motion.
Desires geometry of the resulting motion field. Implementations may return the resolution of the original data. In derived classes, this could be parameters set by user.
Implements CmdOpticalFlowBase.

protectedvirtual |
The result is stored in this channel pack.
Derive the timestep needed further below for [m/s] scaling of the vectors (algorithm produces raw results in pixel scale).
Copy metadata from dataset1 (src1 ~ src2)
Create array for "horizontal" motion (uField component)
Create array for "vertical" motion (vField component)
Implements CmdOpticalFlowBase.
Retrieves the intensity images used as a basis of motion analysis.
IMPORTANT: DataSet<CartesianDst> below will read properties.
Implements CmdOpticalFlowBase.
