Cannot Find The I2R Dataset On The Internet.

I have been studying a paper and I noticed that they were using video from a dataset called I2R. I tried searching for this dataset but wasn’t able to find it. Does it have a different name or is this dataset not available publicly?

Specifically, the paper mentioned the WaterSurface dataset, Campus, Waving trees, fountain, curtain and switch light datasets.

I am looking for these datasets to apply a background/foreground separation algorithm.
