New Pupil Capture Routine release:

Improved Pupil Detection:

The new Pupil detector is more sophisticated and should preform much better. The False Positive rate (ghost pupils) has been dramatically reduced.

• Pupil detection now pre-filters contours based on curvature properties.

• Ellipse fitting now utilizes fitting error to discard bad ellipses

• Our detector now matches and combines contour segments to find a maximally supported ellipse.

• The result is now augmented with a confidence measure (from 0 to 1).

Improved Point Display

GL points now have custom shaders for improved display. This means that Linux users that experienced square points should now see proper circle points.

Proper Logging

Pupil now uses a proper logging system and stream information into logfiles in the user_settings dir.

Bugfixes

A few small bugs have been smashed.
