Seed shape database

The database of seed shape was made with results published  or new measurements done. In general the method is always the same: 1) search for a geometric model that fits the contour of a given seed image and 2) calculate the percent of similarity between seed image and geometric figure (J index). For the more common geometric figures (cardioid, ellipse, oval) only the images giving results over 90 are included in the database. This results in a reduced number of species included but the advantage is that the species represented are associated with a given geometric model with high accuracy.
