A representation for observing local image content is proposed for the purpose of considering the distinguishing characteristics of visual content that tends to draw a human observers gaze. Within this representation, the spectral profile distinguishing fixated from non-fixated locations is considered. Finally, the possibility of designing saliency operators based on the proposed local magnitude spectrum representation is explored, revealing a promising domain for predicting human gaze patterns.
