Detecting Resized JPEG Images by Analyzing High Frequency Elements in DCT Coefficients

Resampling Detection in Digital Images: A Survey

“…Toshihiko Yamasaki et al [16] gave very simple approach which can be applied to conventional liner resizing methods such as nearest neighbor as well as to non-linear resizing method such as seam carving. Major drawback of this method is required human intervention in output image before taking any decision of resizing.…”

Gradient-based global features for seam carving

“…Although several retargeting methods have been developed, such as mesh-deformation-based techniques [4][5][6] and some combinations of multiple methods [7], seam carving still remains an effective tool due to the simplicity and the scalability. Seam carving has expanded in applications, such as for video sequences [8], stereo images [9], image compression [10,11], tamper detection [12,13], and particular images having high image detail concentration [14].…”
