Abstract :
Recently has been reported that spectral saliency detection methods provide state-of-the-art performances in predicting human eyes fixations. However, key information about the perceptual behavior of the human visual system (HVS) is mostly neglected in developing new saliency methods. Adding amplitude spectrum information, based on the contrast sensitivity of the HVS, combined with the phase spectrum of the quaternion Fourier transform (QFT), a human gaze prediction model is proposed. Comparative tests results proved that the proposed method outperforms most of the quaternion spectral based existing models.
