[Blog Post] MSI at last!

Nice!
This seems to confirm that Tepenec's book number is indeed 19.

I didn't even notice the number there, thought it was some strange embellishment under the signature.

Just in case, some basic information about these enhanced images. The models I use are trained on a set of pixel values for some 500 tiny areas of the images (about 3x3 pixels each), about half of these areas are taken from points where there is obvious (on MSI TIFFs) text ink or there obviously should have been some text ink (short empty areas of pen strokes for which only the beginning and the end are clearly identifiable) and the other half are from portions of the page where there is no ink visible and no ink expected. What's important is the model has no access to spacial information (pixel coordinates). So, it's extremely unlikely that the model will introduce spurious artifacts resembling anything like pen strokes. Generally, if the processed image shows a clear line, stroke or blob, especially not within the actual training area (which, for now, is the right margin of 1r only) it means this feature is genuinely present in the TIFFs and not introduced by the model. Even though the feature could be something other than an ink trace.

Which brings me back to 116v. On the processed images I made from MSI there is some strange large squiggle at the bottom right corner of the page, which looks like a signature. I'm not sure if this feature was discussed before.

All four of the models I use consistently pick parts of this squiggle as ink. I cannot see it at all on the visible light scans. Here's one of the models which is particularly good at not picking anything but ink, which still shows parts of this feature clearly.

Here is an overlay of this feature over a scan of 116v.

What could that be?
