"Orientation" feature in MeasureObjectAreaShape module




Could you tell me more about the Orientation feature in MeasureObjectAreaShape module? I don’t know how to interprete the given values.
I would also like to know:

  1. if it is possible to determine the orientation of an object (example: the filopodia of a cell) in relation to a line (or vector) representing a source of chemoattractive molecules.

  2. if it is possible to manually define vectors for filopodia instead of outlining them.

Thanks a lot!


The ‘Orientation’ feature is calculated using Matlab’s regionprops function. For more information, please read :
