Content Aware Media Retargeting for still images using Seam Carving

ABSTRACT When changing height and width of image traditional techniques for image resizing are oblivious to the content of image. A simple operator seam carving is used for image and video retargeting. This seam carving operator is used for content aware image resizing to reduce or expand image size. According to seam carving method every object in the image must be scaled down proportionally. Pixels in image which are belonging to most interesting parts of image are preserving and pixels which are belonging to most uninteresting parts of image are removed. By repeatedly inserting seams in vertical and horizontal directions we can increase size of image or the aspect ratio of image can be changed. Seam carving technique can also be used for enhancing the content of image and removal of object from the image by applying successive operation of the seam carving operator. This paper discuss problem in object removal with seam carving and distortion of image contents when inserting excessive seams in image.
