Image Analysis Using Gabor Transforms: Correlated with Human Saccadic Movement Data to Identify the Human Visual Search Strategy

Abstract

This thesis investigated whether a relationship exists between the Gabor Correlation Coefficient (GCC) magnitudes of fixation points for a set of images viewed by six subjects and the human visual search strategy. A couple of different relationships were investigated. First, the data were analyzed to determine if the GCC magnitudes of human fixation points predicted the time ordered sequence of human fixation points during the performance of a visual search. Second, the data were analyzed to determine if there was a significant difference between the GCC magnitudes of the human fixation points and the GCC magnitudes of a random set of fixation points. Finally, the data were analyzed to ascertain whether there was a difference between the GCC magnitudes of the fixation points at the beginning of the visual search and the GCC magnitudes of the fixation points at the end of the visual search.
