Biologically Motivated Salient Regions Detection Approach

A biologically motivated salient regions detection approach is proposed to identify the salient regions within complex natural images. Multi-scale image features such as intensity, color and orientation are extracted to get some feature maps. The log spectra of the feature maps are analyzed in frequency spectrum domain and the spectra residual are extracted. Then the corresponding feature saliency maps are constructed in spatial domain and theses feature saliency maps are combined to an integrated saliency map. The salient regions are detected in terms of the integrated saliency map. Computer experimental results show that the proposed method successfully detects salient regions in many natural images and artificial images.
