Original image-assisted tamper detection（OIA-TD）

We propose an original image-assisted tamper detection method named OIA-TD which rank 2 among 1471 teams in Analyticup: Falsified image tampering detection-track 2

dataset structure

We use the primary tampered image as auxiliary information and the secondary tampered image at the same time as input to the model.

• primary tampered image

• secondary tampered image

model structure

We propose a model based encoder-decoder structure.
