Interest point detectors (e.g. SIFT, SURF, and MSER)  have been successfully applied to numerous applications  in high level computer vision tasks such as object detection,  and image classification. Despite their popularity,  the perceptual relevance of these detectors has not  been thoroughly studied. Here, perceptual relevance is  meant to define the correlation between these point detectors  and free-viewing human fixations on images. In  this work, we provide empirical evidence to shed light on  the fundamental question: “Do humans fixate on interest  points in images?”. We believe that insights into this  question may play a role in improving the performance  of vision systems that utilize these interest point detectors.  We conduct an extensive quantitative comparison  between the spatial distributions of human fixations and  automatically detected interest points on a recently released  dataset of 1003 images. This comparison is done  at both the global (image) level as well as the local (region)  level. Our experimental results show that there exists  a weak correlation between the spatial distributions  of human fixation and interest points.
