node js and jsfeat/cascades about jsfeat HOT 1 OPEN

I had trouble with cascades too. jsfeat.bbf.face_cascade is undefined in jsfeat version 0.0.8 from npm. From what I read, the HTML5 canvas dependency was removed, so I'm not sure what the problem is.

However, I was able to get it working by copying node_modules/jsfeat/cascades/bbf_face.js, changing jsfeat.bbf on the third line (which is the last line) to module.exports, and then manually injecting it into jsfeat like so:

jsfeat.bbf.face_cascade = require('./bbf_face.js').face_cascade;

After that you can set it up like normal:

jsfeat.bbf.prepare_cascade(jsfeat.bbf.face_cascade);

I didn't try the HAAR detector, but presumably that's what all the other cascade files are for, and I imagine the same workaround would probably work.
