Thank you for the message. I'll be sure to file a bug then. This happens in firefox as well. The OpenCV.js library is compiled from C++. When i create a `new cv.Mat()` and add it to the array and delete it afterwards it does not garbage collect it even tho its not used anymore in the application with no reference to it. I don't know a way to manually call the garbage collection which I dont think is possible in V8, is it?
