Direct Model Usage

If you want to use the models directly with Python:

pip install ultralytics huggingface_hub

from ultralytics import YOLO

# Load model from Hugging Face
model = YOLO('UrielGC/spectrai-IR-YOLO-10FG')

# Run inference on an IR spectrum image
results = model.predict(source='path/to/ir_spectrum.png')

# Visualize results
results[0].show()

Training Data

• Domain: Infrared Spectroscopy
• Format: YOLO (normalized bounding box coordinates)
• Resolution: Optimized for typical IR spectra images
• Annotation Format: .txt files with class ID and normalized coordinates

---

Model Architecture

• Base Model: YOLOv11l
• Framework: Ultralytics
• Input Size: Configurable (typically 640x640)
• Output: Bounding boxes with class predictions and confidence scores

Dataset Format

The model expects input images in the following format:

dataset/
├── images/
│   ├── train/
│   │   └── *.png, *.jpg
│   └── val/
│       └── *.png, *.jpg
└── labels/
    ├── train/
    │   └── *.txt
    └── val/
        └── *.txt

Label Format

<class_id> <x_center> <y_center> <width> <height>

Where coordinates are normalized to [0, 1] relative to image dimensions.
