# 🌴 Palm Oil Ripeness Agent (n8n + YOLOv8)

This project uses a custom-trained **YOLOv8** model to detect the ripeness of Palm Oil Fresh Fruit Bunches (FFB). It features a local Python FastAPI server and a Streamlit Dashboard, both integrated into an **agentic n8n workflow**.

## 🚀 Project Overview

1. **Vision Engine:** YOLOv8 Nano (Custom-trained on MPOB-standard datasets).
2. **Inference Server:** FastAPI (Python) for n8n integration.
3. **Demo Dashboard:** Streamlit UI for drag-and-drop batch testing.
4. **Intelligence:** MongoDB Atlas Vector Search for similarity-based reasoning.

## 🛠 Prerequisites

* Python 3.10+
* n8n (Desktop or Self-hosted)
* MongoDB Atlas Account (with Vector Search index enabled)

---

## 📦 Setup Instructions

### 1. Environment Setup

```bash
git clone <your-repo-url>
cd palm-oil-ai
python -m venv venv
# Windows: venv\Scripts\activate | Mac: source venv/bin/activate
pip install ultralytics fastapi uvicorn streamlit python-multipart pillow

```

### 2. Dataset & Training

1. Download the dataset from [Roboflow](https://universe.roboflow.com/assignment-vvtq7/oil-palm-ripeness/dataset/5/download/yolov8)
*Or you can also find your own separate source of datasets. Make sure the file/folder format structure is consistent, especially the .yaml file.
2. Extract into `/datasets`.
3. **Train the model:**
```bash
python train_script.py

```


4. Copy the resulting `best.pt` from `runs/detect/train/weights/` to the project root.

### 3. Running the Demo (Streamlit)

To show the interactive dashboard to colleagues:

```bash
streamlit run demo_app.py

```

* **Local URL:** `http://localhost:8501`

### 4. Running the API for n8n

To connect your AI to n8n workflows:

```bash
python main.py

```

* **Endpoint:** `POST http://localhost:8000/detect`
* **Payload:** Form-data with key `file`.
