Abstract: The traditional spectral-based saliency detection methods have many drawbacks, such as unstable detection result and lack of bionics meaning. This paper presented a new saliency detection method based on spectrum tuning using lateral inhibition mechanism. The new method tunes the Fourier spectral self-adaptively using multiple nonlinear tune forms to inhibit the redundant image features and enhance the saliency image features, and therefore the salient region could be detected effectively. We tested this method on both real natural images and artificial pictures such as psychological patterns.The results indicate that our method is more efficient than other methods in aspects of saliency region detection rate, salient region contour detection and high salient region contrast.
