Difference between ADE20k and SceneParsing150

Is SceneParsing150 the original snapshot of ADE20k?

Multiple papers refer to ADE20k has having 20210 training images, which matches [this description of SceneParsing150](http://sceneparsing.csail.mit.edu/#:~:text=Training%20set-,20%2C210,-images%20). Can someone clarify if this is the case?

This is important if we want to compare our results with [this leaderboard](https://paperswithcode.com/sota/semantic-segmentation-on-ade20k). Confirmation will be greatly appreciated.

Thank you.
