color and shape and examples!

[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.

If you are so inclined to see an example go to this link and click on this
link: <<http://tera-assoc.dyndns.org:8081/Peters_Images/>> and select purple
original and purple extract.



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,

I have a similar problem so maybe we can help each other.  Can you
tell me 1) where to find the color plugin ( I don't see anything on
the plugin page and didn't find it via Google), and 2) how you're
using the template matching plugin (It seems like you'd need to have
pictures where the flowers were all the same size for it to work).

From the example it looks like it did a pretty good job.  Is that the
output from the template matching plugin?  What's not working
correctly?
