Saliency detection and region of interest extraction based on multi-image common saliency analysis in satellite images.

•ROIs are effectively extracted from satellite images by multi-image common saliency analysis.•Salient detection based on feature clustering among multiple multispectral images is proposed.•Panchromatic image saliency analysis is introduced by computing co-occurrence histogram.•A novel fusion strategy is proposed to obtain the multi-image saliency maps.
