In response to your comment: I gave you the link, which contains code to do essentially what you want to do, it is up to you to decide if it fits your circumstances or is useable at all, by running it and dissecting the code. Does it matter if it is 'from the center area'? If it detects neighbouring cells and includes them or not according to a rule that you define, it would do so even if it started in one of the corners. That is the nature of the process.
