| Summary: | <p>A) Two consecutive image frames are used to calculate the optical flow via the Farnebäck algorithm, which utilizes a multi-level resolution pyramid to estimate intensity displacements between the two frames. B) Once the flow field is calculated, a threshold Th is applied to the magnitude of the individual flow vectors, leaving only flow vectors with a magnitude above Th. C) The pixels associated with the remaining flow field form a binary mask to estimate where the cell is in the image. D) The mask is closed and filled to create the segmented perimeter of the cell.</p> |
