Visual saliency detection in image using ant colony optimisation and local phase coherence

A new visual saliency detection approach is proposed. The proposed approach exploits the ant colony optimisation technique to measure the image's saliency via depositing the pheromone (through ants' movements) on the image. Furthermore, the ants' movements are steered by the local phase coherence of the image. Experimental results are presented to demonstrate the performance of the proposed approach.
