Implementation of recurrence quantification analysis (RQA) to quantify the similarity of two fixation sequences (or scanpaths).
Based on the paper Anderson, Nicola C., et al. "A comparison of scanpath comparison methods." Behavior research methods 47.4 (2015): 1377-1392.
It implements the following metrics:
- Cross-recurrence
- Determinism
- Laminarity
- Center of recurrence mass
