| # Dataset Card for COMSATS Structured Video Tampering Evaluation Dataset (CSVTED) |
|
|
| <!-- Provide a quick summary of the dataset. --> |
|
|
| The COMSATS Structured Video Tampering Evaluation Dataset (CSVTED) provides a three-level dataset structured by tampering quality and video complexity, designed to support research in video forensic analysis. |
|
|
| ## Dataset Details |
|
|
| The dataset consists of 1047 videos: 133 original + 914 tampered in various formats (avi, mp4, mov). |
| These were captured using multiple cameras and lighting conditions (morning, noon, evening, night, fog). |
| We included various tampering types, both spatial and temporal: |
| - Frame duplication |
| - Deletion |
| - Insertion |
| - Copy-move |
| - Splicing |
| - Event-Object-Person (EOP) based tampering |
|
|
| We used SSIM and Optical Flow to select optimal positions for duplication, insertion, or deletion. This helps maintain visual consistency and avoids abrupt changes, especially by matching object motion direction. |
|
|
| ## Dataset Structure |
|
|
| The dataset consists of zipped video files in either avi, mp4 or mov formats. |
|
|
| From the original untampered videos: |
| - Original.zip (133 videos) |
|
|
| 7 sets of manipulated videos were derived: |
| - EOP-Frame-Deletion.zip (20 videos) |
| - EOP-Frame-Duplication.zip (20 videos) |
| - EOP-Frame-Insertion.zip (20 videos) |
| - Frame-Deletion.zip (260 videos) |
| - Frame-Duplication.zip (291 videos) |
| - Frame-Insertion.zip (293 videos) |
| - Spatial-Tampering.zip (10 videos) |
|
|
| ## Filename Structure |
|
|
| The information regarding the number of tampered frames and the location of tampering is embedded in the filename/title of each tampered video. |
| For example, consider the following tampered video: **010_Del_021_030_Shop Banners** |
|
|
| The components of the filename represent the following: |
| - **10** represents the number of frames deleted. |
| - **Del** represents the type of tampering, i.e., **Frame Deletion**. |
| - **021** represents the location of the tampering (Localization). |
|
|
| Thus, frames **021 through 030**, including both the 21st and 30th frames, were deleted from the original/untampered video to generate the tampered video. |
|
|
| Similarly if the title of video is: **010_Ins_017_026_Slides** |
|
|
| The components of the filename represent the following: |
| - **010** represents the number of frames inserted. |
| - **Ins** represents the type of tampering, i.e., **Frame Insertion**. |
| - **017** represents the starting location of the insertion. |
| - **026** represents the ending location of the insertion. |
|
|
| Therefore, the insertion operation starts at the **17th frame and ends at 26th** frame. |
