Video seam carving with perspective line structure preservation

When people want to transform the size of image or video into different kinds of ratio, it is possibly lost the important and significant object while doing this operation. Various strategies have been tested for achieving this issue such as seam carving. It can retain the crucial objects and remove the insignificant pixels repeatedly, resulting in the content-aware image/video. Such ordinary method presents vital problem is that it could destroy the line structure and shape of the object, which can be easily find out by the viewers. The video seam carving will also cause the continuous problem because of the motion. In this paper, we provide the state-of-the-art strategies focus on maintaining the perspective line structure in video, especially in vehicle video recorder. We also compare proposed method with the other papers. The complete experiments would be illustrated in the website http://video.minelab.tw/pl/PLseamCarving.
