To accelerate the Grabcut algorithm,a modified Grabcut algorithm is presented by using resolution reduction preprocessing.The proposed method reduces the size of original images and applies Grabcut on it.The preprocessing needs less time and converges much faster.In order to get accurate details,the algorithm applies the last Grabcut iteration on original images.Whether Grabcut is applied on a lower resolution image or an original image,it is proved that their Gibbs energies decrease at the same time.Experimental results show it is a feasible method to accelerate the Grabcut algorithm.
