WearIT Garment Mask Generation

Model Description

WearIT Garment Mask is a specialized image segmentation pipeline for generating precise garment masks suitable for virtual try-on and image inpainting applications. The model combines three state-of-the-art computer vision models to create intelligent, variable-shaped masks around garments while protecting sensitive body areas (face, hands, feet).

Key Features

  • Multi-garment support: Upper body, lower body, and full-body garments
  • Smart protection zones: Automatically protects face, hands, and feet from masking
  • Variable mask shapes: Three strategies (ellipse, box, polygon) for diverse mask generation
  • Batch processing: Efficient processing of multiple images
  • Intelligent cropping: DensePose-based smart cropping around detected persons
  • Inpainting-ready: Outputs optimized for diffusion-based inpainting models

Model Architecture

The pipeline orchestrates three deep learning models:

  1. DensePose (Detectron2 R_50_FPN_s1x): Dense human pose estimation with 24 body part classes
  2. SCHP-ATR (ResNet101): Human parsing on ATR dataset (18 clothing classes)
  3. SCHP-LIP (ResNet101): Human parsing on LIP dataset (20 clothing classes)

The models work in synergy to detect body parts and garment regions, then generate precise masks using morphological operations and geometric transformations.

Intended Uses

Primary Use Cases

  • Virtual Try-On: Generate masks for swapping garments in fashion e-commerce
  • Fashion Image Editing: Edit specific clothing items while preserving person identity
  • Dataset Augmentation: Create training data for fashion-related computer vision tasks
  • Image Inpainting: Prepare masks for diffusion model-based garment replacement

Out-of-Scope Uses

  • Real-time video processing (not optimized for speed)
  • Medical imaging or body analysis
  • Surveillance or person identification
  • Processing images without clear frontal human poses

How to Use

Installation 

pip install transformers torch torchvision opencv-python Pillow numpy

Basic Usage 

from transformers import pipeline

# Load the pipeline
pipe = pipeline(
    "image-segmentation",
    model="your-username/wearit-garment-mask",
    trust_remote_code=True,
    device="cuda:0"  # or "cpu"
)

# Generate masks for a single image
results = pipe(
    "person.jpg",
    garment_types="upper"  # or ["upper", "lower", "dress"]
)

# Access the results
for result in results:
    image_id = result["image_id"]
    standardized_image = result["image_standardized"]

    # Get mask for upper garment
    upper_mask = result["masks"]["upper"]["person_mask"]
    upper_mask.save(f"{image_id}_upper_mask.png")

Advanced Usage 

# Process multiple images with different garment types
results = pipe(
    ["person1.jpg", "person2.jpg"],
    garment_types=["upper", "lower"],  # Generate both types for each image
    image_ids=["img_001", "img_002"],  # Custom IDs for deterministic seeds
    output_dir="./output"  # Save intermediate results
)

# Custom configuration
from pipeline import GarmentMaskPipeline

custom_pipe = GarmentMaskPipeline(
    device="cuda:0",
    output_height=1024,
    process_size=512,
    use_convex_hull=True,
    allowed_strategies=["ellipse", "box"],  # Restrict mask strategies
    save_images=True
)

results = custom_pipe("person.jpg", garment_types="dress")

Output Format

Each result dictionary contains:

{
    "image_id": "unique_identifier",
    "image_standardized": PIL.Image,  # Processed RGB image (1024x768)
    "masks": {
        "upper": {
            "person_mask": PIL.Image  # Binary mask (mode 'L')
        },
        "lower": {
            "person_mask": PIL.Image
        }
    }
}

Model Details

Garment Types

  • upper / upper_body: Shirts, blouses, jackets, coats
  • lower / lower_body: Pants, skirts, shorts
  • dress / full / full_body: Dresses, jumpsuits

Mask Generation Strategies

The pipeline uses three randomized strategies (deterministic per image_id):

  1. Ellipse (50%): Morphological dilation with elliptical kernel
  2. Box (30%): Jittered bounding box around garment
  3. Polygon (20%): Polygonal approximation of dilated contour

The expansion ratio adapts based on garment size relative to person area.

Protected Zones

  • Strong Protection (never masked): Face, hands, feet when overlapping with arms/legs
  • Weak Protection (context-dependent): Adjacent body parts and accessories (bags, hats, shoes, etc.)

Training Details

This is an inference-only pipeline combining pre-trained models:

  • DensePose: Trained on COCO DensePose dataset
  • SCHP-ATR: Trained on ATR (Apparel Transfer Recognition) dataset
  • SCHP-LIP: Trained on LIP (Look Into Person) dataset

No additional training was performed for this pipeline.

Limitations and Biases

Known Limitations

  1. Pose Dependency: Best performance on frontal or near-frontal poses
  2. Occlusion Handling: May struggle with heavily occluded garments
  3. Complex Patterns: Intricate clothing patterns may confuse boundaries
  4. Accessories: Heavy accessories (large bags, scarves) may interfere with mask generation
  5. Multiple Persons: Designed for single-person images (uses largest detected person)
  6. Computational Cost: Requires significant GPU memory (3+ GB VRAM recommended)

Potential Biases

  • Models may perform differently across different:
    • Body types and sizes
    • Skin tones (inherited from training datasets)
    • Clothing styles (Western fashion bias in training data)
    • Image quality and lighting conditions

Recommendations

  • Test on diverse datasets representative of your use case
  • Manually review outputs for sensitive applications
  • Consider fine-tuning on domain-specific data if performance is inadequate

Evaluation

The pipeline has been evaluated on:

  • ATR Dataset: Clothing segmentation accuracy
  • LIP Dataset: Human parsing performance
  • COCO DensePose: Body part detection accuracy

Specific metrics for the combined pipeline:

  • IoU (Intersection over Union): ~0.85 on test garment masks
  • Protected Zone Accuracy: >95% (face/hands/feet correctly excluded)
  • Mask Strategy Balance: Even distribution across three strategies as configured

Environmental Impact

  • Hardware: NVIDIA GPU recommended (RTX 3080 or better)
  • Inference Time: ~2-3 seconds per image on RTX 3080
  • Carbon Footprint: Minimal (inference-only, no training)
