Window for Tracking

The particle tracking takes place in a rectangular window within the frame buffers. Anything falling outside the window will not be considered as a particle for tracking purposes. Permanent reference points should normally be outside the window. The contents of the window may be further masked with options specified by [B Background removal] and [C Contour masking].

Specify window using which buffer ?

The tracking window is specified interactively using the normal DigImage window selection submenu. This entry allows the window to be produced with the aid of an image already acquired by specifying the buffer in which the image may be found. Any buffer may be used for this process. The buffer selected will be made the current output buffer.

Window Selection: Set tracking window

The DigImage window selection submenu may then be used to specify the tracking window. Remember that reference points should normally lie outside the tracking window. For further help on specifying DigImage windows, see [H Help] within the submenu.
