Salient region detection is a key research field in image processing.An approach for calculating salient regions using multi-scale analysis in the frequency domain was proposed.First,low-level features of the image at different scales were extracted.By analyzing the amplitude spectra and phase spectra of feature maps in the frequency domain,a corresponding saliency map was constructed in the spatial domain.Using the saliency map,the salient regions in an image can be identified.This method was tested on both natural images and artificial images.The experimental results showed that this approach quickly extracted salient regions which were consistent with human visual perception.The method performed well even in images with a high density of noise.
