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.
