🎯 Model Description

This is a Duck-Net model fine-tuned for polyp segmentation in colonoscopy images. The model is based on a U-Net architecture with Duck-inspired multi-scale feature extraction blocks for superior medical image segmentation performance.

📊 Model Performance

Validation Dice Coefficient: 92.88%
Validation Jaccard Index: 48.92%
Dataset: Kvasir-SEG (1000 colonoscopy images)
Training Time: ~83 minutes on GPU
Model Size: ~29.6 MB

🚀 Quick Start

python

from huggingface_hub import hf_hub_download
import torch
import torch.nn as nn

# Define the model architecture
class DuckNet(nn.Module):
    def __init__(self, img_size=(256, 256), num_classes=3):
        super(DuckNet, self).__init__()
        # ... (model definition)
        
    def forward(self, x):
        # ... (forward pass)
        return torch.sigmoid(output)

# Download and load model
model_path = hf_hub_download(
    repo_id="ibrahim313/ducknet-polyp-segmentation",
    filename="pytorch_model.bin"
)

model = DuckNet(img_size=(256, 256), num_classes=3)
model.load_state_dict(torch.load(model_path, map_location='cpu'))
model.eval()

# Inference
import albumentations as A
from albumentations.pytorch import ToTensorV2

transform = A.Compose([
    A.Resize(256, 256),
    A.Normalize(mean=[0.485, 0.456, 0.406], std=[0.229, 0.224, 0.225]),
    ToTensorV2()
])

# Process image
transformed = transform(image=your_image)
input_tensor = transformed['image'].unsqueeze(0)

with torch.no_grad():
    prediction = model(input_tensor)
    binary_mask = (prediction > 0.5).float()
