I am trying to update legacy code that uses the no longer supported call to
opticalFlowClass = vision.OpticalFlow('OutputValue', ...
'Horizontal and vertical components in complex form', 'Method', method);
which as the call indicates, outputs a M x N matrix in complex form. The current call, for example
opticalFlowClass = opticalFlowHS;
flow = estimateFlow(opticalFlowClass, video);
outputs a flow object with the components
Due to dependencies elsewhere in the code and to avoid a complete rewrite, I would like to use the components from the new call to form the matrix in the complex form of the old call. However, I was unable to find any documentation how the complex form was created. My question is
What is the structure of the complex form and how was it created from the components and orientation?
Any links to old documentation that explain this would be much appreciated.
Edit: I should add that I speculate that
but I have no support for this
