Hello all.
I'm contacting you because I am considering starting a new open source
project to solve a specific problem: training and evaluating objects
detection algorithms.
Hundreds of students have been there before: "I want to create a program
that detects objects in images".
They choose a dataset for training (e.g. INRIA pedestrians), a feature
descriptor (e.g. HOG), a machine learning method (e.g. linear SVM), and
then, they write the code to get it all together.
In the best case they will take bits and pieces from multiple places and
spend a few weeks on the glue code. In the worst case they will spend months
reimplementing existing methods.
It is time to stop the madness.
Training detectors for objects detection in images is a specific and well
defined problem.
It is time to share our effort and build a reference open source tool to
solve this common problem.
We should have an open source tool that provides all the common bits, the
glue and allows us to focus on what we really care: the algorithms.
In some sense
OpenCv<http://www.google.com/url?sa=D&q=http%3A%2F%2Fopencv.willowgarage.com%2F>2.2
helps a lot to the task, however OpenCv is aimed to be a generic
library
not a specific application framework. In that sense it will never provide
the desired "install, run, see the graphs coming out" experience.
Also ROS.org
<http://www.google.com/url?sa=D&q=http%3A%2F%2FROS.org>helps a lot the
task, by providing a generic framework to create and
exchange software modules, along with standard tools for messages passing,
data storage and exploration. However this framework by itself has a non
negligible learning curve and it is unfamiliar to anyone outside the
robotics community.
I currently have my own idea of how things could be. However before
creating "yet one more framework" I would like to have *your* input on
the topic.
I have created a short form to collect your opinions. I would be very
glad if you could help me go in the right direction by giving your input.

The form is anonymous and the results are public.
Based your opinions and ideas I will do my best to move forward an usable
open source solution.
Further information will be posted at

Best regards,

ps: If you are interested do not hesitate to send me a message. You can
contact me via github as "rodrigob".
