Scribes and authorship of the text

[ReneZ]

I have some ideas for how to correct for this. Assume that a word's "true" bounding box oriented along the direction of writing has width w and height h. Also assume that the direction of writing is at some angle q relative to the page's horizontal orientation. The ratio of the area of the "horizontal" bounding box, analogous to what Voynichese.com provides, to the area of the "true" bounding box is given as:

R = ((w*sin(q)+h*cos(q))*((w*cos(q)+h*sin(q))/(w*h)

At small q, it's not so bad, but it's a non-negligible problem.

As a next step, I want to try and automatically provide an initial correction at the line level by calculating the average slope of a given line of text, converting that to an angle, and then applying a line-average correction using the formula above treating the slope angle as q (or at least as an input parameter for how to calculate q). That doesn't correct for the Scribe 4 circles, but it could tighten everything else up.

I did these things a couple of years ago. Converting the horizontal boxes to slanted boxes using a formula like this cannot work without some assumptions, and when the angle is 45 degrees (mod 90) the problem becomes singular.
It is very ill-determined for angles around these values.
I have average slopes for all non-curved loci.
