Since the empirical mode decomposition (EMD) lacks strict orthogonality, the method of orthogonal empirical mode decomposition is innovationally proposed by this paper. The primary thought of this method is to obtain the intrinsic mode function (IMF) and the residual function by auto-adaptive band-pass filtering. OEMD is proved to preserve strict(More)
A variety of computational models based on different views for visual saliency detection have emerged in computer vision. In this paper, we combine RGB space and Lab space to represent original features of each image patch in the vector form, and employ principal component analysis (PCA) to select effective features. The saliency cue is obtained by(More)
