Structure preservation of image using an efficient content-aware image retargeting technique

Abstract

The presence of a wide range of high- and low-resolution devices renders the images to experience changes in respect to aspect ratio and size for better adaptability. This paper proposes a novel and effective technique that vanquishes the problems encountered in the conventional seam carving method. To achieve minimum distortion in salient objects of the image, the proposed technique restricts intersection or overlapping of multiple seams in the horizontal and vertical direction and bypasses them to the neighboring low energy pixel. The proposed technique hinders the pixel selection from a single row or column beyond the defined threshold so as to save the image information and reduce distortion at a single location. To justify the effectiveness of the proposed technique, results have been presented in comparison with the five state-of-the-art image retargeting techniques. Compared with the conventional techniques, this technique shows remarkable results in terms of low distortion percentage. The proposed technique also produces excellent results for shrinkage and enlargement of a single image multiple times.
