Calculate RMS #18

Closed Joelgranados closed 10 years ago

Joelgranados commented 10 years ago

this is an alternative approach for general plant shape regularity evaluation. Computation is based on fitting ellipses with same second central moments as the region covered by an actual plant. RMS is then calculated as the ratio between the foci of the ellipse and its major axis length. In contrast with first Eccentricity, this parameter does not take into consideration distribution of leaf mass (in first case, eccentricity is usually higher for plants with relatively long petioles considering the leaf blade).

Not really sure how to address this. And I have found no hints in previous matlab code

Joelgranados commented 10 years ago

I managed to figure out a way to calculate RMS with eccentricity.
