As far as the stereo images, the matching between the left and right image and the disparity should be considered, and the matching and the resizing of disparity are fused on the retargeting of the stereo images. A resizing method by using stereo extension of seam carving is proposed, which can keep the image content more precise during adjusting the size of the image, adjust the size of disparity, and ensure the consistency between the left and right images.
