What is use of orientation in Cell morphology analysis?

3 views (last 30 days)
Greetings Users.
I am a biology major trying to understand cell's (as in animal/human cells) morphology using matlab. I found the orientation feature on region props and wanted to know what it represents. The definition is just an angle between a base line and the major axis. Is there a way to theoretically explain how the orientation corresponds to how the object (the cells) is aligned in the plane.
For example: I have a numerical value of a single object as 48.51447079 for the feature "orientation". What does it mean ?

Orientation property of regionprops function returns an angle between the x-axis and the major axis of the ellipse that has the same second-moments as the region. I came across few related questions :-
Hope that helps!
