This function estimates the scaling parameters for two sets of fixation data using the Hausdorff distance as an optimization objective.
Arguments
- x
A data frame or matrix containing the x coordinates of the first set of fixations.
- y
A data frame or matrix containing the y coordinates of the second set of fixations.
- lower
A numeric vector of length 2 specifying the lower bounds for the scaling parameters (default is c(0.1, 0.1)).
- upper
A numeric vector of length 2 specifying the upper bounds for the scaling parameters (default is c(10, 10)).
- window
A numeric vector of length 2 specifying the time window to restrict the fixations in `y` (default is NULL, which considers all fixations).
