I will soon be working on Random Forests. I have read a couple of papers on it and got an idea how it works. Can any one point me to a link from where I can download RF code (c++) such that its node test criteria and features to be extracted could be edited?
If you are familiar with R, I would recommend going over the source code of randomForest package (it is basically a C code -> http://cran.r-project.org/web/packages/randomForest/). To my best knowledge, this implementation is the closest one to Breiman's original random forest implementation (his fortran code is here http://www.stat.berkeley.edu/~breiman/RandomForests/cc_software.htm).
If you are interested in a regression problem, Geurts' extremely randomized forest (ERF) approach is also worth to look at -> http://www.montefiore.ulg.ac.be/~geurts/Software.html. ERF has similarities to random forest and used for image vision problems (I do not know your domain but just wanted to mention about it because of Stefan's comment). The provided software on the provided link also has random forest implementation however it works only for regression problems.

Dear,
please check this youtube video, where I explain how Random Forest algorithm works

Late answer: OpenCV has a Machine Learning module where random forest is implemented in C++ and you can modify that code as you want.
