Hello, I am working on a stereoscopy vision project and I have the intention to use ROS in this project. But I have a couple of questions before starting and I would be very grateful for your help. 1- Is it possible to edit the source code of a package (for example stereo_image_proc) and recompile it to be used in an other project? 2- For stereo_image_proc, could I specify the paths of two images (from my hard disk) and make them inputs for the stereo_image_proc in order to calibrate, rectify and extract disparity map from them? Thank you in advance
