Given the existing relationship between color and the degree of
maturity in the fruit, two data sets were considered, the first
corresponds to the olive fruit samples during different dates in its
harvest period. Fig. 8 shows some examples of colors that is taking
the olive during maturation period.
In addition to the previous set of data, images corresponding to
the grape seeds were used. This dataset was chosen due to have
been recently proposed several methods to estimate the degree
of phenolic maturity in the grapes based on images of the seed
given the existing relationship between the appearance of this
and the fruit maturity. Fig. 9 shows the appearance that is taking
the seed during its different phenolic stages.
