magento 2.3.5 image cache being auto generated

I found that images in /cache/folder is auto generated on demand if they aren’t cached and get request the re-generated from the original if exists and according to the sizes for specific settings, but it can be confusing as to which cache folder is for which sizes, E.G: small, thumbnail, base etc…

Where could I find this dynamic created folder, is in DB table ?

Thanks
