Correlation Analysis Between Eye Gaze and Image Content of the Natural Scene Pictures

Study of the eye movement characteristics of humans when watching pictures can help to improve the analysis accuracy of calculation models in the visual salient region. This study selected 100 natural images from the image library and the tested eye movement data of subjects were recorded by eye trackers, features of human eyes at gaze points were analyzed when freely viewing pictures (no task instructions), emphasizing on the study of the picture’s first fixation point and second point fixation ratio which can complete characterization of picture content. Application method of eye movement data in the calculation model of visual significant area is put forward by combining with characteristics of the picture.
