Abstract: 

Seam carving is one of content aware image retargeting techniques. In this method, a path of pixels with lowest energy, called seam, crossing from top to bottom or from left to right in an image is extracted. By removing or inserting seams, size of the image can be changed. Speed and quality are two main parameters in seam carving. In this paper a new method for speed enhancement of seam carving is proposed. The input image is decomposed into odd and even subimages and searching for seams is performed in parallel in these subimages. Compared to the original seam carving, the proposed method improves the speed at least by two times while maintain image’s quality unchanged. Previous seam searching algorithms can be utilized in our method or it can be combined with other parallel processing schemes. Finally, image quality of the proposed seam carving is improved.
