Too hard. High level math. For later.

Signed-off-by: Ethan Wellenreiter <ewellenreiter@gmail.com>
Whites out the background pretty well. Changed it
to an adaptive threshold first and then use contours to get a mask.
Also using morphology to clean up said mask.

Doesn't work well when text is near the edge.

Signed-off-by: Ethan Wellenreiter <ewellenreiter@gmail.com>
Instead of bluring the edge, now I used inpainting
to use the page colour to fill in the background so it's uniform.

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

Signed-off-by: Ethan Wellenreiter <ewellenreiter@gmail.com>
Exactly as the title says.

Title^^^^

Signed-off-by: Ethan Wellenreiter <ewellenreiter@gmail.com>
Just removed unnecessary sorting from the function.

Signed-off-by: Ethan Wellenreiter <ewellenreiter@gmail.com>
Using just OTSU thresholding with some morphology as it's similar
quality but a lot faster.

Signed-off-by: Ethan Wellenreiter <ewellenreiter@gmail.com>
The mask used for inpainting wasn't correct (it seems).
Updated it to use the correct mask for inpainting.

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

Signed-off-by: Ethan Wellenreiter <ewellenreiter@gmail.com>
Changed the technique it uses. Seems to work a little better.

It use to leave little scraps of the line. Adjusted it so it doesn't.
