Live Camera Streaming in Android

问题:

I know how to give effect of Pencil Sketch to image but my question is different from this.

I found Pencil Camera app on Play Store which is using Live Camera Streaming in its Application.

After showing image you already know what my question will be.

Question : How can I achieve this?

I know about Camera Color Effects but it has not such option. Will OpenCV do this?
