Horizon matters: Image re-targeting using horizon cues

In this work, we propose an effective method for improving the aesthetics of a given image based on the horizon information extracted from the image. We employ the vanishing line detection method to determine the horizon and then adjust the angle of the scene to level the horizon. The image is thus retargeted to highlight the visual appearance. In addition, our method can also be applied on the task of distinguishing the image acquisition methods. For example, hand held phones typically don´t have perfect level horizons. Experimental results demonstrate the performance of our proposed method.
