| # Gen-Arena |
|
|
| Gen-Arena is a text-to-image evaluation benchmark for compositional prompt following and reference-conditioned generation. Each sample contains a natural-language generation prompt, optional reference images, named entities, and fine-grained constraints. |
|
|
| Gen-Arena is introduced in the paper *SCOPE: Structured Decomposition and Conditional Skill Orchestration for Complex Image Generation* as a human-annotated benchmark with entity- and constraint-level specifications. |
|
|
| This package contains 300 samples across 6 categories: |
|
|
| | Category | Samples | Unique image files | Reference slots | |
| | --- | ---: | ---: | ---: | |
| | `1-cartoon` | 50 | 56 | 56 | |
| | `2-game` | 50 | 103 | 104 | |
| | `3-sports` | 50 | 50 | 50 | |
| | `4-entertainment` | 50 | 50 | 50 | |
| | `5-competition` | 50 | 0 | 0 | |
| | `6-ceremony` | 50 | 30 | 50 | |
|
|
| ## Files |
|
|
| - `data/gen_arena.jsonl`: unified metadata file with all 300 samples. |
| - `reference_images/<category>/`: reference images grouped by category. |
|
|
| All image paths in `data/gen_arena.jsonl` are root-relative paths. |
|
|
| ## Schema |
|
|
| Each row in `data/gen_arena.jsonl` has the following fields: |
|
|
| - `id`: unique sample id. |
| - `category`: category directory name. |
| - `prompt`: generation prompt. |
| - `reference_images`: list of objects with `id` and root-relative `path`. |
| - `reference_image_paths`: list of root-relative image paths. |
| - `num_reference_images`: number of reference images for the sample. |
| - `entities`: list of named entities and optional reference links. |
| - `constraints`: list of fine-grained constraints with `id`, `type`, `text`, and `depends_on`. |
| - `num_entities`: entity count. |
| - `num_constraints`: constraint count. |
| - `constraint_type_counts`: counts by constraint type. |
|
|
| Constraint types are `attribute`, `layout`, and `relation`. |
|
|
| ## Loading |
|
|
| ```python |
| from datasets import load_dataset |
| |
| dataset = load_dataset("json", data_files="data/gen_arena.jsonl", split="train") |
| print(dataset[0]["prompt"]) |
| print(dataset[0]["reference_image_paths"]) |
| ``` |
|
|
| Reference images can be loaded by joining each `reference_image_paths` value with the dataset root. For example, image paths follow the form `reference_images/1-cartoon/1-cartoon_001_Tiggy.jpg`. |
|
|
| ## Notes |
|
|
| - `5-competition` is intentionally text-only and has no reference images. |
| - Some samples share the same reference image file after exact duplicate cleanup. |
| - The license and redistribution status of reference images should be verified before public release. |
