Transparent Tube Classifier

Transparent Tube Classifier

A binary image classifier that distinguishes between:

• transparent_alone 🧪 — A transparent tube by itself
• transparent_with_blue 🧪💙 — A transparent tube paired with a blue tube

Quick Start

Using Pipeline (Easiest)

from transformers import pipeline

classifier = pipeline("image-classification", model="Siddanna/transparent-tube-classifier")
result = classifier("your_tube_image.jpg")
print(result)
# [{'label': 'transparent_with_blue', 'score': 0.99}, {'label': 'transparent_alone', 'score': 0.01}]

Manual Inference

from transformers import AutoImageProcessor, AutoModelForImageClassification
from PIL import Image
import torch

# Load model and processor
model = AutoModelForImageClassification.from_pretrained("Siddanna/transparent-tube-classifier")
processor = AutoImageProcessor.from_pretrained("Siddanna/transparent-tube-classifier")

# Load and classify image
image = Image.open("your_tube_image.jpg")
inputs = processor(image, return_tensors="pt")

with torch.no_grad():
    logits = model(**inputs).logits

predicted_class = logits.argmax(-1).item()
label = model.config.id2label[predicted_class]
confidence = torch.softmax(logits, dim=-1)[0][predicted_class].item()

print(f"Prediction: {label} (confidence: {confidence:.2%})")

Training Details

Architecture

• Base: DINOv2-base (Vision Transformer B/14), pretrained on LVD-142M (142M curated images)
• Head: Linear classifier (768 → 2)
• Method: Linear probe — backbone is frozen, only the classification head is trained
• Why DINOv2?: DINOv2's global self-attention captures the full image context, which is critical for detecting whether a blue tube is present anywhere in the scene alongside the transparent tube

Hyperparameters

• Learning rate: 1e-3 (with cosine schedule)
• Warmup steps: 50
• Batch size: 16
• Weight decay: 0.01
• Training epochs: 4 (converged at epoch 1)

Data Augmentations

• RandomResizedCrop (scale 0.7-1.0)
• RandomHorizontalFlip
• RandomRotation (±15°)
• ColorJitter (brightness=0.3, contrast=0.3, saturation=0.2, hue=0.05)

Training Curves

Epoch	Train Loss	Eval Loss	Eval Accuracy
1	0.032	0.019	100%
2	0.011	0.002	100%
3	0.002	0.001	100%
4	0.004	0.010	99.5%

For Production Use with Real Images

The model is currently trained on synthetic data. For best results with your actual tubes:

Step 1: Collect Real Photos

Take 50-100+ photos per class of your actual tubes:

data/
├── train/
│   ├── transparent_alone/     # Photos of transparent tube alone
│   └── transparent_with_blue/ # Photos of transparent + blue tube
└── test/
    ├── transparent_alone/
    └── transparent_with_blue/

Step 2: Re-train

# Clone the training script
# Option A: Linear probe (fast, good with 50+ images/class)
python train.py --data_dir ./data --freeze_backbone --hub_model_id your-username/tube-classifier

# Option B: Full fine-tune (better with 200+ images/class)
python train.py --data_dir ./data --learning_rate 5e-5 --hub_model_id your-username/tube-classifier

Tips for Collecting Good Training Data

• Vary backgrounds: different surfaces, lighting conditions
• Vary angles: slightly different camera positions
• Vary distances: close-up and farther away shots
• Include edge cases: partially occluded tubes, different orientations
• Match deployment conditions: use the same camera/environment you'll deploy in
