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 ?
