# π· SCIMD-6: Source Camera Identification β Mobile Devices Dataset
|
| 5 |
+
## π Overview
|
| 6 |
+
**SCIMD-6** is a carefully curated image dataset developed at **Bapatla Engineering College** to support research in **source camera identification** using images from **mobile devices**. The dataset contains **6315 RGB images**, acquired from **six different smartphones** under **diverse real-world conditions**.
|
| 7 |
+
The mobile devices used are Moto G64 5G (1006 image),Moto G85 5G(1037 images),
|
| 8 |
+
Nothing A001(1036 images), Realme 8 Pro(1001 images),
|
| 9 |
+
Redmi 14C 5G(1014 images),Xiaomi M2101K6P(1221 images). Total 6315 images.
|
| 10 |
+
|
| 11 |
+
π *Note*: Slight imbalance exists across classes but overall distribution is fairly uniform.
|
| 12 |
+
## π Image Characteristics
|
| 13 |
+
- π **Resolution**: All images are resized to **224Γ224** pixels for compatibility with CNN architectures.
|
| 14 |
+
- π€οΈ **Conditions**: Captured in a variety of **uncontrolled environments**, including:
|
| 15 |
+
- Indoor and outdoor
|
| 16 |
+
- Sunny and rainy weather
|
| 17 |
+
- Casual perspectives and variable lighting
|
| 18 |
+
- π€³ **Capture Style**: Intentional lack of discipline in framing adds **real-world complexity** for model robustness testing.
|
| 19 |
+
## π Included Files
|
| 20 |
+
- π A zip file consisting of `Motog64_5G/`, `Motog85_5G/`, ..., `Xiaomi_M2101K6P/`: Folders containing 224Γ224 RGB images per mobile device.
|
| 21 |
+
- π `merged_common.csv`: A metadata file containing **EXIF information** (Exchangeable Image File Format ) extracted from all images (e.g., Make, Model, ExposureTime, FocalLength).
|
| 22 |
+
## π― Intended Use
|
| 23 |
+
This dataset is intended for tasks such as:
|
| 24 |
+
- πΈ **Source Camera Identification (SCI)**
|
| 25 |
+
- π¬ **Image Forensics and Provenance Analysis**
|
| 26 |
+
- π€ **Fine-grained Classification and Transfer Learning**
|
| 27 |
+
- π§ **Deep Learning Model Benchmarking in Forensic Settings**
|
| 28 |
+
π Potential Applications of the Dataset
|
| 29 |
+
This dataset, although primarily designed for source camera identification using mobile device images, supports a wide range of research directions and practical applications:
|
| 30 |
+
1. Source Camera Identification (SCI)
|
| 31 |
+
β’ Classification of images based on the originating mobile device using intrinsic sensor characteristics.
|
| 32 |
+
β’ Enables research in PRNU-based techniques and camera model/device fingerprinting.
|
| 33 |
+
2. Image Forensics and Metadata Consistency Analysis
|
| 34 |
+
β’ Verification of metadata integrity using image content.
|
| 35 |
+
β’ Detection of inconsistencies in EXIF fields such as shutter speed, ISO, focal length, and timestamp.
|
| 36 |
+
β’ Applicable in detecting tampered or manipulated media.
|
| 37 |
+
3. Shutter Speed and ISO Estimation (Regression Tasks)
|
| 38 |
+
β’ Pixel-to-metadata learning: predicting EXIF fields like ISO speed rating or exposure time directly from the image content.
|
| 39 |
+
β’ Useful for modeling camera behavior and building metadata synthesis pipelines.
|
| 40 |
+
4. Image Quality Assessment (IQA) and Denoising
|
| 41 |
+
β’ Training and benchmarking denoising models under real-world noise conditions (e.g., high ISO settings).
|
| 42 |
+
β’ Correlation of EXIF parameters with perceptual quality for no-reference IQA research.
|
| 43 |
+
5. Environmental and Scene Classification
|
| 44 |
+
β’ Scene-type inference (indoor/outdoor, sunny/cloudy, low-light conditions) based on visual content and EXIF cues.
|
| 45 |
+
β’ Aids in tasks like environmental awareness, adaptive imaging, or low-light enhancement.
|
| 46 |
+
6. Image Provenance and Authorship Verification
|
| 47 |
+
β’ Attribution of images to devices for media forensics and misinformation detection.
|
| 48 |
+
β’ Combines device classification with temporal and spatial metadata for provenance tracing.
|
| 49 |
+
7. Training and Evaluation of Robust Vision Models
|
| 50 |
+
β’ Offers real-world diversity in lighting, context, and device pipeline characteristics.
|
| 51 |
+
β’ Supports robustness evaluation of CNNs, Vision Transformers, and vision-language models in uncontrolled environments.
|
| 52 |
+
|
| 53 |
+
The SCIMD-6 dataset is publicly available on multiple trusted platforms for broad accessibility and reproducibility.
