We should have a list of properties to be compared. 
I think these should suffice
```python
[
    'area',
    'bbox',
    'moments_central',
    'centroid',
    'convex_area',
    'eccentricity',
    'equivalent_diameter',
    'euler_number',
    'extent',
    'filled_area',
    'moments_hu',
    'major_axis_length',
    'max_intensity',
    'mean_intensity',
    'min_intensity',
    'minor_axis_length',
    'moments',
    'moments_normalized',
    'orientation',
    'perimeter',
    'solidity',
    'weighted_moments_central',
    'weighted_centroid',
    'weighted_moments_hu',
    'weighted_moments',
    'weighted_moments_normalized' ]
