Content aware image resizing technique has become more important with the development of device technology. Although the seam carving method produces high-quality resized images, it requires high computational complexity. In this paper, we propose a faster content-aware image resizing technique. Our method performs seam carving in wavelet transform domain. This approach reduces the computational complexity of image resizing. To avoid breaking in the spatial continuity of an image, our method reduces the image width by scaling a seam width down instead of carving it out. In addition, the decomposition level can be decreased adaptively to avoid distortion. We show our method produces resized images with less distortion and less computational cost than the seam carving method.
