A vision-based fully automated approach to robust image cropping detection

作者:

Highlights:

• This work presents an automated approach for detecting asymmetrically cropped images.

• The shift of the image center w.r.t. the principal point is used to assess cropping.

• A novel metric based on a Monte Carlo analysis is proposed to evaluate cropping.

• Experiments show the effectiveness and robustness of the proposed method and metric.

• Heuristic criteria are also introduced to discard intractable images at run time.
