This study intends to measure the degree of correlation/similarity between the subjective gaze points (obtained by eye tracking experiments) and the objective interest points of several well-known detectors such as Harris and SURF. For each of the latter, we look for the best setting in term of maximization of likeness with the gaze points. For this task, the Earth Mover's Distance (EMD) is used to compare two data-sets with different cardinalities. We also used ANOVA to measure the influence of each parameter involved in the detectors' settings as well as the possible introduced bias. The conclusions of this study are related to the suitability of each detector to estimate the subjective gaze points.
