Abstract: Global features and local features are very important for texture visual perception.This paper investigated the influence of the global features and local features of texture on the eye movement pattern and the relationship between the eye movement pattern and visual similarity selection.Firstly,the texture images were synthesized by separately controlling global textural features and local textural features with primitive,grain,and point configuration (PGPC) texture model,which is a mathematical morphology based texture model.In the experiment,three scenes were utilized.For each scene,three textures (A,B,and S) were included.Secondly,an experiment was conducted on visual similarity selection to acquire eye movement data while the subjects were viewing the visual similarities of texture scenes under the task of “Which texture is more similar to texture S,texture A or texture B?”.Experimental data were obtained with an eye tracker Tobii T60 by conducting two tests on 89 subjects.The collected eye-tracking data were analyzed in terms of fi-xation point variance in each ROI and fixation transfer count between different ROIs.Analysis results indicate that the global features and local features of texture influence the eye-movement pattern,namely,the texture image that is glo-bally similar to the compared texture contains dispersed fixation points,and the texture image that is locally similar to the compared texture contains concentrated fixation points.Besides,the final visual similarity selection is related to the visual search between different ROIs.
