Nowadays, images are being viewed on the slimmest and the smallest display devices which is a challenge for various image resizing techniques and algorithms. Traditional methods have been used to change the height and width of the image which are ignorant to the content of the image. Effective resizing of images should focus on image content more than anything else. A manageable technique called seam carving is used for image and video retargeting. Seam carving is therefore used in the reduction or expansion of the height and width ratio known as the aspect ratio. The most important objects in an image are conserved and the inessential objects are edited by placing seams across, which remove the pixels of that object and hence reduce the size of the image. This method can be used for object removal, image enhancement, reducing the size of image, expanding or enlarging the size of image. This article looks upon the basics of seam carving, its types, its basic algorithm, problems in object exclusion and reduction in size of different images.
