Visual Saliency Map Algorithm Using Spatiotemporal Features
Lu We · Video Engineering · 2015
A new algorithm for computing spatio-temporal saliency maps is proposed in this paper. Firstly,the optical flow vectors of absolute motion is estimated. Then the background motion vectors to obtain the temporal saliency maps is calculated. Secondly,color contrast and texture information is used to calculate the spatial saliency maps. Finally,spatio-temporal saliency maps by fusing spatial and temoral maps is got. Experimental results show a better performance when compared to several state-of-the-art temporal saliency models.
