Hi, <br>
can I attach it to ros nodes, which are detectors?<br>

Hi Peter,<br>
<br>
regarding detectors evaluation, one typical way to evaluate them
in research is using <a moz-do-not-send="true"
href="http://www.vlfeat.org/benchmarks/index.html">VLBenchmarks</a>,
a MATLAB framework for testing image feature detectors and
descriptors which some parts are based on the original <a
moz-do-not-send="true"
href="http://www.robots.ox.ac.uk/%7Evgg/research/affine/#software">code</a>
of <a moz-do-not-send="true"
href="http://www.inrialpes.fr/lear/people/Mikolajczyk">K.
Mikolajczyk </a>and others just uses only Vlfeat. However,
OpenCV has a slightly implementation in C++ based on that
mentioned original code [<a moz-do-not-send="true"
href="http://docs.opencv.org/master/da/d9b/group__features2d.html#gaa7cacd54220a6da4ee05748a0329b754">1</a>]
[<a moz-do-not-send="true"
href="https://github.com/Itseez/opencv/blob/master/modules/features2d/src/evaluation.cpp#L454">2</a>].
In my opinion, if you are using this OpenCV implementation then
the code you want to release should go in the existent <a
moz-do-not-send="true"
href="http://wiki.ros.org/vision_opencv">vision_opencv</a>
which has some implemented OpenCV apps.<br>

Hi,<br>
<br>
I want to publish a package on the ros website.<br>
It is about evaluation detectors in Computer Vision.<br>
<br>
Usually, the detector spits out, if and where it found
a desired object.<br>
You can read in XML files, which have saved the
ground truth and says where the object really is
located.<br>
</blockquote>
<blockquote class="gmail_quote" style="margin:0 0 0
.8ex;border-left:1px #ccc solid;padding-left:1ex"> The
package pops up a window where you will see the
rectangle of the ground truth and the rectangle of the
detector. So you can see, if those rectangles are
overlapping, the detector is right and saves the
percentage in<br>
file. This list will be read in a script, which shows
up a ROC curve of your database.<br>

Automatic evaluation of (changes to) vision
algorithms would be very useful. I'm very interested
to see your package.</div>

Please, help me to put this package on the ros webpage

<div class="gmail_default"
style="font-family:arial,helvetica,sans-serif">I
have no experience publishing packages on the ROS
website. However, the code is normally hosted
elsewhere, like github. Would it be possible for you
to publish the package publicly first (for example
on github) and give us all the possibility to test
it out? Undoubtedly that's a good first step towards
getting it published on the ROS website too.<br>
