PETools v1.7.18: Optional tracking

Minor changes

• Tracking can be disabled. If so, humans will still receive ids, but the ids won't persist among frames and no coordinates smoothing will be applied.
• Added a configuration class that controls how text is drawn in the visualization utilities.

PETools v1.7.17: Fix cold start problem

Fixes

• In previous version ProportionsLengthCalculator had chache initialized with None what could case a runtime error. Now the cache is initialized with zero.

PETools v1.7.16: Changing format of humans storage

Breaking changes:

• Information about humans (poses) is contained in dictionaries instead of tuples. All the key components (drawing, angles computation) were adapted to new format.

Minor changes

• Added infinity check in angles computation.
• Added small constant to division in angles computation to avoid zero division.

PETools v1.7.15: Changed points correction

Major changes

• ratio2 in the points correction algorithm is set to 0.25 (0.4 was previously).

PETools v1.7.14: Removed rotation correction and changed points correction

##Major changes

• Rotation correction of the Z coordinate is removed.
• ratio2 in the points correction algorithm is set to 0.4 (0.25 was previously).

PETools v1.7.12: Increasing ratio for distant points

Major changes

• Increasing ratio for distant points to make the correction more rare.

PETools v1.7.11: Remove correction for close points in elbows

fix(angle_math): shoulder points indexing

PETools v1.7.10: Fix shoulder point indexing

Fixes

• Fix shoulder points indexing during 3D skelton rotation correction.

PETools v1.7.9: Fix order of elbow points preprocessing

Merge remote-tracking branch 'origin/master'

PETools v1.7.8: Remove elbow points correction

Major changes

• Remove elbow points correction.
