%X Since the spectral residual (SR) method of the visual attention model has poor contrast saliency maps and unsatisfactory detection of saliency details. In this paper, we propose a saliency detection method based on spectrum analysis by discussing the relationship between spectral characteristics of the image and the saliency. This method keeps the phase spectrum and tunes the amplitude spectrum using a piecewise non-linear function for the purpose of inhibiting the redundant information and enhancing the saliency image information. Experimental results show that saliency detection method based on phase spectrum and tuning amplitude spectrum (PTA) obtains a saliency map, which has better contrast, and allows for a better deteetion of the details of the saliency information.
