OpenCV Error: Assertion failed ((src.type() == CV_8UC1 || src.type() == CV_8UC3) && src.type() == dst.type() && src.size() == dst.size() && src.data != dst.data) in bilateralFilter_8u, file /home/travis/miniconda/conda-bld/work/opencv-2.4.11/modules/imgproc/src/smooth.cpp, line 1925

Try adding the following line before frame=cv2.bilateralFilter
frame.astype(np.uint8)

This error can also probably be removed if using OpenCV2.4.8 but I don't think there is any reason for it to not work with 2.4.11. Either ways you can also remove that line altogether because without bilateral filtering too the code will work almost with the same effeciency.
