retinex element on ubuntu 16.04 (arm64)

Dear,

I would run Retinex element on ARM64 based ubuntu 16.04/18.04, and installed gstreamer1.0-plugins-bad with apt-get. However it might do not have retinex element in ARM64 package. (gst-inspect1.0 retinex returns no element message)

How can I try this element on ARM64 H/W?

Thanks,
