## Summary

LayoutBench-COCO is a diagnostic benchmark that examines layout-guided image generation models on arbitrary, unseen layouts.
Unlike [LayoutBench](https://huggingface.co/datasets/j-min/layoutbench), LayoutBench-COCO consists of OOD layouts of real objects and suports zero-shot evaluation.
LayoutBench-COCO measures 4 skills (Number, Position, Size, Combination), whose objects are from [MS COCO](https://cocodataset.org/).
The new 'combination’ split consists of layouts with two objects in different spatial relations, and the remaining three splits are similar to those of LayoutBench.

## Skill Details

### Skill 1: Number.

We define two layouts for 2∼10 objects and use 40 COCO objects, resulting in 720 total layouts (= 2×9×40). We name the layouts with 2∼4 and 8∼10 objects as few and many splits. The layouts are paired with captions with a template `“a photo of [N] [objects]”`.

### Skill 2: Position.

For each of boundary and center splits, we define four layouts with 40 COCO objects, resulting in 320 total layouts (= 2 × 4 × 40). The layouts are paired with captions with a template `“a photo of [N] [objects]”`.

### Skill 3: Size.

For each of tiny and large splits, we define nine layouts with 40 COCO objects, resulting in 720 total layouts (= 9×2×40). The layouts are paired with captions with a template `“a photo of [N] [objects]”`.

### Skill 4: Combination.

This skill measures whether a model can generate two objects that commonly or uncommonly appear in the real world. For each of the three spatial relations (holding, next to, sitting on), we define three layouts without specifying objects. For each of the three relations, we manually define 20 object pairs of COCO objects for common and uncommon splits. For example, (1) ‘person sitting on chair’ is more common than (2) ‘elephant sitting on banana’ in real life. This results in 360 total layouts (= 2×3×3×20). The layouts are paired with captions with a template `“[objA] [relation] [objB]”`.

# Use of LayoutBench-COCO

Step 1. Download LayoutBench-COCO and Generate Images from Layouts

Please see [Step 1 README](https://github.com/j-min/LayoutBench-COCO/blob/main/image_generation/README.md) for instructions on downloading LayoutBench-COCO and generating images from layouts.

Step 2. Run Evaluation

Please see [Step 2 README](https://github.com/j-min/LayoutBench-COCO/blob/main/yolov7/README.md) for instructions on running evaluation on LayoutBench-COCO.
