Compute 2D Flow Field starts the computation of optical flow for the slice set in Frame , using the Algorithm . Display redisplays the flow field in a separate window. The size of the window is determined by Scale , and the visualization format by Mapping type . Open flow field opens an existing flow field in the Burkitt format. Errors to clipboard copies angular error data including deviations to the clipboard Copy central frame shows the stack slice for which the flow was computed.
Graph opens a window that shows a graph of measured versus true flow.
A true flow field needs to be loaded for this to work. Frame sets the slice for which the flow is computed. The frame is set to the central slice in the stack by default. Scaling sets the enlargement for Display. The parameters not mentioned above are very specific to each algorithm.
