How do I get JeVois to work with Haar Cascade for right eye?

0 votes

Not great at programming but can usually find a tutorial that will give me a step by step guide. Not in this case,, I would just like my jevois to work of the haarcascade_righteye_2splits.mxl detection but can't figure out how to either write a program for it or edit an existing module. I have spent many hours searching..

Any pointers would be appreciated.

Are you interested in Python? If so, check out the tutorials on how to get started with Python and OpenCV on JeVois here:


then, you would basically write your detector in python, or port it from some existing python sample. For example this one:


or other hits returned by "haar cascade python" search words.

Your task then is to take the code given in such a tutorial and port it to JeVois. The Dice Counting turorial of JeVois shows how to do this step by step, though for a different vision algo:


One last thing is to access your xml files; if you put them in JEVOIS:/share/eye.xml on the microSD, then you access them as /jevois/share/eye.xml in your code. Basically, the root of the microSD as exported by the "usbsd" JeVois command is accessible as /jevois/ from code.
