Groundtruth of spliced images in dataset CASIA 1.0

• CASIA 2.0 groundtruth dataset is avaiable at: https://github.com/namtpham/casia2groundtruth

• Please notice that the authors made mistakes in naming the files. If you already downloaded the dataset, I recommend you to rename the tampered images using the commands in the excel file. Otherwise, you can use the modified version of dataset.

• Since the owners' server is no longer avaiable, I upload the dataset to my drive, including original dataset and the modified version (renaming dozens of images in tampering folder). Please visit one of the following links to download (~90 MB):

• Google Drive: https://bit.ly/37TuHRx

• One Drive: https://bit.ly/3nXyYJw

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

Authentic images: 800 images (8 categories, 100 images in each category).

Au_ani_0001.jpg

Au: Authentic

ani: animal category

Other categories: arc (architecture), art, cha (characters), nat (nature), pla (plants), sec, txt (texture)

Tampering images

a. Spliced image

    Sp_D_CND_A_pla0005_pla0023_0281.jpg

• Sp: Splicing
• D: Different (means the tampered region was copied from the different image)
• Next 4 letters stand for the techniques they used to create the images. Unfortunately, I don't remember exactly.
• pla0005: the source image
• pla0023: the target image
• 0281: tampered image ID

b. Copy-move images

    Sp_S_CND_A_pla0016_pla0016_0196.jpg

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