e6c6f03 introduced bug where parameters can be changed but are not validated. Causes almost certain crashes in OpenCV

I should probably use the old code I had in the GUI python node for validation

Also, not just validate the data, but also catch exceptions and handle them gracefully (right now it just crashes)
