How to Use

Installation

pip install torch torchvision pillow

Basic Usage

import torch
from torchvision import transforms
from PIL import Image

# Load the model
model = torch.load('model.pth')
model.eval()

# Prepare the image
transform = transforms.Compose([
    transforms.Resize((256, 256)),
    transforms.CenterCrop(224),
    transforms.ToTensor(),
    transforms.Normalize(mean=[0.485, 0.456, 0.406],
                        std=[0.229, 0.224, 0.225])
])

# Load and preprocess image
image = Image.open('currency.jpg').convert('RGB')
image_tensor = transform(image).unsqueeze(0)

# Make prediction
with torch.no_grad():
    outputs = model(image_tensor)
    probabilities = torch.softmax(outputs, dim=1)
    predicted_class = torch.argmax(probabilities, dim=1).item()
    confidence = probabilities[0, predicted_class].item()

# Currency mapping
currencies = {
    0: '10 Taka',
    1: '100 Taka',
    2: '1000 Taka',
    3: '2 Taka',
    4: '20 Taka',
    5: '200 Taka',
    6: '5 Taka',
    7: '50 Taka',
    8: '500 Taka'
}

print(f"Predicted: {currencies[predicted_class]}")
print(f"Confidence: {confidence:.4f}")

Using from Hugging Face Hub

import torch
from transformers import AutoModel, AutoImageProcessor

# Load model and processor
model = AutoModel.from_pretrained("your-username/efficientnetb0-bangladeshi-currency")
processor = AutoImageProcessor.from_pretrained("your-username/efficientnetb0-bangladeshi-currency")

from PIL import Image
image = Image.open('currency.jpg')

# Process and predict
inputs = processor(images=image, return_tensors="pt")
with torch.no_grad():
    outputs = model(**inputs)
    logits = outputs.logits
    predicted_label = logits.argmax(-1).item()

Input Format

• Image Size: 224 × 224 pixels (resized from variable sizes)
• Color Channels: RGB (3 channels)
• Normalization: ImageNet normalization
  • Mean: [0.485, 0.456, 0.406]
  • Std: [0.229, 0.224, 0.225]

Limitations

• The model is trained specifically on Bangladeshi currency images
• It may not perform well on:
  • Heavily damaged or worn currency
  • Non-standard lighting conditions
  • Currency images at extreme angles
  • Other countries' currency

Training Data

The model was trained on a dataset of naturally photographed Bangladeshi paper currency images, providing robust real-world performance.

Future Improvements

Potential enhancements could include:

• Data augmentation for better robustness
• Multi-angle and multi-lighting condition samples
• Damaged currency detection
• Real-time video stream processing
