This repository contains supplementary materials for the submission "*Interpretable Oracle Bone Script Decipherment through Radical and Pictographic Analysis with LVLMs*".

---

## 📋 Contents Overview

### 1. Appendix (`Appendix.pdf`)

The appendix section includes:
- **Limitations**: Detailed discussion of current method limitations and future works.
- **Parameter Analysis**: Experimental analysis of key hyperparameters in RDM and their impact on performance.
- **Qualitative Results**: Extended qualitative results showcasing comprehensive decipherment examples and visualizations.

### 2. PD-OBS Dataset (`PD-OBS/`)

The **PD-OBS (Pictographic Decipherment of OBS)** dataset is a novel oracle bone script pictographic decipherment dataset constructed for this work.

> **Note**: Due to supplementary material size constraints, only a small-scale subset is included in the current submission for demonstration purposes. The complete dataset will be publicly released during the camera-ready stage.

#### 2.1 Dictionary Directory (`PD-OBS/dictionary/`)
Contains comprehensive character analysis data:
- **Character List of KangXi Dictionary**
- **Authoritative Dictionary Definitions**
- **Radical Analysis**
- **Pictographic Analysis**
- **Character-ID Mapping**

#### 2.2 Image Directory (`PD-OBS/img/`)
Organized into three subdirectories:
- **`regular/`**: Modern Chinese character writing style images
- **`ancient/`**: Ancient Chinese character writing style images
- **`obs/`**: Corresponding oracle bone script character images

> All images are linked to their respective labels through the ID system defined in the dictionary.
