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 the following link to download: (~2.6 GB)
[Update 2022/04/14] Revised dataset: https://bit.ly/2QazgkG

I removed the download link of the original dataset to avoid the confusion. If you need it, feel free to email me.

[Update 2019/09/30]: In this version, almost the noises in the previous version are handled. The file names are also revised carefully.
List of duplicate authentic images provided by another researcher.

Please notice that the authors made many mistakes in naming the files. People who download the original dataset (before 2021/04/20) please 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.
