shape and color recognition

[TERA EPA]

Hello,

The "template matching" plug-in that was developed by Dr. Walter O'Dell has
been very helpful in selecting flowers based on their shape. In addition, we
are using a plug-in developed by Dr. Christopher Coulon for refining our
search for objects, in this case flowers, that are a particular color. It
would be optimum to combine shape and color recognition.



I have adapted Dr. Coulon's plug-in for use on the flower, *Prunella
vulgaris. *The petals of *Prunella* have been identified using this
particular color-recognition plug-in, however, the center of the flower is
not identified as a ROI. The purple flowers of *Prunella *often do not
enclose a unit, the count and area of these flowers remains inaccurate.  This
is because the color recognition plug-in depends on a completed object's
circumference. The purple petals are often discontinuous.



Do you have any suggestions on how we might incorporate the two plug-ins? Or
is there an existing plug-in that will refine our search to incorporate both
color and shape?



Thank you,

Emily Cavaliere
