An effective vector model for global-contrast-based saliency detection.
Journal of Visual Communication and Image Representation(2015)
摘要
•A basic vector model is derived to perform the global-contrast-based saliency detection.•Two principles are provided to use the vector model effectively.•The new vector model is developed by modifying the construction of the basic model.•New model improves the detection precision, especially for large salient objects.•Experimental results show the effectiveness of the proposed method.
