Groundtruth images of tampering dataset CASIA 2.0

Groundtruth of spliced images in dataset CASIA 2.0

  • CASIA 1.0 groundtruth dataset is avaiable at: https://github.com/namtpham/casia1groundtruth

  • Groundtruth dataset can be downloaded directly from this repository.

  • Recently, I received several requests of the original dataset since the server is no longer available. I upload this dataset to my Drive to spread this dataset to the research community. Please visit one of the following links to download: (~2.6 GB)

  • Google Drive: https://bit.ly/2Jx9ROM

  • One Drive: https://bit.ly/34TpwiJ

  • Update (09/30/2019): in this version, almost the noises in the previous version are handled. The file names are also revised carefully.

Please notice that the authors made many mistakes in naming the files. I recommend you to rename the tampered images using the commands in the excel files. Originally, it was reported that there are 5123 tampered images, including 3274 copy-move images and 1849 spliced images. However, mistakenly classified files are renamed as follows.

No. of images Originally named as Re-classified as
39 Copy-move images (TP_S_) Spliced images (S->D)
60 Spliced images (TP_D_) Copy-move images (D->S) 
    After renaming the files, the number of copy-move and spliced images are 3295 and 1828, respectively.

Due to the lack of manual file, I write up here the naming convention:

Authentic images:

Au_ani_00001.jpg Au: Authentic ani: animal category Other categories: arc (architecture), art, cha (characters), ind (indoor), nat (nature), pla (plants), txt (texture)

Tampering images

a. Spliced image

    Tp_D_CRN_S_N_cha00063_art00014_11818.jpg
  • Tp: Tampering
  • D: Different (means the tampered region was copied from the different image)
  • Next 5 letters stand for the techniques they used to create the images. Unfortunately, I don't remember exactly.
  • cha00063: the source image
  • art00014: the target image
  • 11818: tampered image ID

b. Copy-move images

    Tp_S_NRN_M_N_pla00020_pla00020_10988.jpg
  • Tp: Tampering
  • S: Same (means the tampered region was copied from the same image)
  • And the rest is similar to case a.
