Recaptured Images Dataset

Content and Format

6 different brands of camera were used to capture 2000 natural images and 2700 finely recaptured images. The resolutions range from 2272 by 1704 to 4256 by 2832. The total download size of this dataset is ~17GB which consists mainly of JPG images and some BMP images.

The 2000 natural images were captured using 5 different brands of camera (Canon, Casio, Lumix, Nikon, and Sony) and are categorised as follows:

The 2700 recaptured images are recaptured from:

  • 100 images taken by the 3 available cameras
  • 100 images downloaded from Flickr website
  • 100 tampered images where about 10% of the total image area has been altered

and categorised as:

  • 300 images recaptured by Canon Powershot A620 DSLR from Philips 19 190B6CG LCD
