Code for Paper "Image Tampering Detection and Localization via Reliability Fusion Map"

Reliability Fusing Map (RFM)

This repository is implementation of "Image Tampering Detection and Localization via Reliability Fusion Map” (RFM). The main contributions are summarized as follows (1) obtaining higher accuracy; (2) reducing computational complexity of clustering; (3) improving localization fineness from 64 x 64 to 32 x 32.

Prerequisites

• tensorflow == 1.7.0
• pandas == 0.23.4
• scipy == 1.1.0
• sklearn == 0.19.2
• matplotlib == 2.2.3
• Pillow == 5.2.0

Usage

• Run pretrain model:

1. You can download pretrain model at: Baidu disk, password=mxqr Google drive

   put unzip folder into code/model/{scope_name}, see {scope_name} in code.config.py

2. Run pre-train test using command:

   python main.py --code.config --action test

   where code.config.py is config file including CNN architecture, dataset name, and so on.
   

   The CNN module pre-train output is a csv file, which format with:

   {f1,f2,f3...,predict_label,true_label,quality_factory}, where f1,f2... is CNN confidence of each camera model.

3. Post-train in experiment folder

---

• You can train your personal pretrain model:

1. Download Drensden dataset into /code/dataset

   python main.py --code.config --action download --name Dresden

2. Generate a tensorflow records file:

   python main.py --code.config --action generator

3. For training process, running command:

   python main.py --conf code.config --action train

4. Making your personal tampering dataset:

   python main.py --conf code.config --action splicing

Result

Results of comparative experiment with method proposed by Bondi et al. and our RFM method. (a)-(c) illustrates cover image, forged image, and ground truth image. (d) and (e) illustrates result of cover image and forged image with RFM algorithm, (f) show result of Bondi et al. We improve localization fineness from 64 x 64 to 32 x 32 (see (e) and (f)).
