🌿 SCOLD: A Vision-Language Foundation Model for Leaf Disease Identification

SCOLD is a multimodal model that maps images and text descriptions into a shared embedding space. This model is developed for cross-modal retrieval, few-shot classification, and explainable AI in agriculture, especially for plant disease diagnosis from both images and domain-specific text prompts.

---

✅ Intended Use

• Vision-language embedding for classification or retrieval tasks
• Few-shot learning in agricultural or medical datasets
• Multimodal interpretability or zero-shot transfer

🧪 How to Use

First clone our repository:

 git clone https://huggingface.co/enalis/scold

Please find detail to load and use our model in inference.py

tokenizer = RobertaTokenizer.from_pretrained("roberta-base")
text = "A maize leaf with bacterial blight"
inputs = tokenizer(text, return_tensors="pt")

# Image preprocessing
image = Image.open("path_to_leaf.jpg").convert("RGB")
transform = transforms.Compose([
    transforms.Resize((224, 224)),
    transforms.ToTensor()
])
image_tensor = transform(image).unsqueeze(0)

# Inference
with torch.no_grad():
    image_emb, text_emb = model(image_tensor, inputs["input_ids"], inputs["attention_mask"])
    similarity = torch.nn.functional.cosine_similarity(image_emb, text_emb)
    print(f"Similarity score: {similarity.item():.4f}")
