Abstract :
In recent years, spectral residual for saliency detection has attracted many attentions because of its good performance and low complexity. In this paper we will discuss some properties of spectral residual: 1) is amplitude important for spectral residual? 2) The effect of resolution for spectral residual. 3) The relationship between spectral residual and edge detection. We also proposed a fast spectrum detection algorithm which only involves addition/subtraction. The results are demonstrated with Bruce and Tsotsos benchmark dataset.
