In addition to exiting a function, the return statement is also used to pass data back to the caller. If a return statement inside a Python function is followed by an expression, then in the calling environment, the function call evaluates to the value of that expression:...

The shapes always expand from inside nuclei, one per nucleus, and evolve towards nucleus boundaries. In the active contour model, contours move based on image appearance information until Eq. (4.20) reaches a stable state, where the associated energy function achieves a minimum value; in the ...
In Python, can I create a global variable inside a function and then use it in a different function?David Blaikie
When a python program is executed, python interpreter starts executing code inside it. It also sets few implicit variable values, one of them is __name__ whose value is set as __main__. For python main function, we have to define a function and then use if __name__ == '__main_...
