Tried with kernel based off of character size but
it didn't work. Also removed old adaptive kernel
which was based off of image size.

Still extracts barcodes and stuff, not just text.
That's the possible thing I see left to fix.

In between testing out using a line morphology.
Can't seem to dial it in for the subclusters.
Want to try combining the old and new technique. That is,
the line morphology for the first full receipt and then the letter
technique for the subclustering.

It does not work if there are small dots near the edge.
For example, if a small bit of a character is detached or
a colon is really low/high.

Need to update text clarifier so that lines aren't
merged together on characters but have updated it so that
there is a deskew in between line clustering.

Tried easyOCR but it was pretty bad so I'm going to try
the pytorch based model TrOCR which uses the MIT Licence.

Updated refined images and also added images of the extracted lines
using the new autocropper and line extraction functions respectively.

Generally extracts the lines well. There might be some errors
in the future so it needs to be checked.

Just adding a little bit of complexity to try and remove some of the
random clumps and spots that appear.

The mask used for inpainting wasn't correct (it seems).
Updated it to use the correct mask for inpainting.

Using just OTSU thresholding with some morphology as it's similar
quality but a lot faster.

As the title says but also adjusted the demoing and specle
thresholding functions so that they work a bit better.

Instead of bluring the edge, now I used inpainting
to use the page colour to fill in the background so it's uniform.
