* primitive line detector (debug version)
* more reliable line detection (but still too much false positives)
* added sorting for fast clusterization
* better line detection
changed detetection to probable model
much better lines identification
* commented out debug images output
* fixed line count
* much better contour removal based on a mask erosion
* reduced mask erosion due to weird image distortion
* better noise reduction (i hope)
* better border remove
* shred-dependent line length
Complement lines feature detector with a better adaptive thresholder. Clean up the code.
