binarize

restruct		threshold
		Reorganized thresholds (binarize). Thresholds are separated, transition to a map model of local thresholds, separation of prefilters and postfilters. Fixed BiModal threshold (similar to Otsu). The "Mode" panel has been reorganized.

select

Changes:

• select content: replacing Wolf threshold with BlurDiv
• output: add scale 3.0 and 4.0
• page layout: add center line.

zones

fill	zones
	Changing the order of the fillzones and adding a mask zone allows you to get different combinations of shading in combination with k-means.

dewarping

dewarping	cylindrical	(nonstable)
	The (nonstable) version of the cylindrical dewarping mesh was finally selected and formalized. This version has failures on the zero column of the grid, which manifests itself in twitching or skew of the first cells, and it is necessary to fine-tune the extreme points to eliminate this effect. But at the same time, dewarping is done properly: the curvature of the upper and lower faces is transferred to all grid lines, in contrast to the (stable)-version of meshing used in other varieties of ST.

k-means

K-Means	Colors	HSV
	K-means based on the HSV color space for the mask. Optionally, a medium color is blended into the white background (with a factor of 1.0, similar to noteshrink). Changed despeckle control. Now it is fully adjustable, keeping the original presets.

color

color	text	zones
	Adding a layer by mask (foreground) in combination with color filters allows you to leave colored text for further processing in third-party programs. Wiener and KNN denoisers allows you to effectively deal with background noise without touching the text.
