The picture contains a table. You task is to identify any merged cells in this table, and output the scope of each merged cell using the JSON format of {'top-left':(x, y), 'bottom-right':(m, n)}. The row id and column id should start from 1.

The merged cell regions are as follows:
{'top-left':(1, 1), 'bottom-right':(2, 1)}
{'top-left':(2, 2), 'bottom-right':(2, 7)}
{'top-left':(3, 2), 'bottom-right':(3, 7)}
{'top-left':(4, 2), 'bottom-right':(4, 7)}
{'top-left':(8, 2), 'bottom-right':(8, 7)}.
