+ # DiffusionPrint Patch Dataset
17
+
18
+ A dataset of 64x64 image patches for contrastive learning of diffusion-based inpainting forensics.
19
+ Each patch comes from either a real image or an AI-inpainted region generated by one of three diffusion models.
20
+
21
+ ## Columns
22
+
23
+ | Column | Type | Description |
24
+ |---|---|---|
25
+ | `image` | `bytes` (PNG) | Lossless 64x64 RGB patch |
26
+ | `master_index` | `int64` | Row index in the original memmap archive |
27
+ | `patch_path` | `string` | Original relative path of the patch |
28
+ | `category` | `string` | `real` or `generated` |
29
+ | `generator_model` | `string` | `none` (real), `sd2`, `sdxl`, or `flux` |
30
+ | `has_positive` | `bool` | Whether this patch has a contrastive positive counterpart |
31
+ | `positive_master_indices` | `string` | Semicolon-separated `master_index` values of positive pairs |
32
+
33
+ ## Pair Structure
34
+
35
+ Positive pairs are patches from the **same spatial location** under different conditions
36
+ (e.g. a real patch and its diffusion-reconstructed counterpart).
37
+ `positive_master_indices` stores semicolon-separated integer indices that resolve directly
38
+ against the `master_index` column -- no filesystem paths needed.
39
+
40
+ ## Generator Labels
41
+
42
+ | `generator_model` | Label int |
43
+ |---|---|
44
+ | `none` (real) | 0 |
45
+ | `sd2` | 1 |
46
+ | `sdxl` | 2 |
47
+ | `flux` | 3 |
48
+
49
+ ## Stats
50
+
51
+ - Total patches: 3,688,480
52
+ - Shards: 37
53
+ - Patch size: 64x64 RGB, lossless PNG
