A user uploads their photo to an app — and the AI must overlay clothing so that it looks natural, considering pose, proportions, and lighting. This is a challenging computer vision task solved by a combination of body segmentation, pose estimation, and image synthesis. We have been implementing such solutions for mobile apps for over five years, using the MediaPipe, HR-VITON, and Metal stack. Our stack includes GAN-based image synthesis, volumetric rendering, and edge computing for on-device parsing.
Usually, a project starts with an audit of the clothing catalog and quality requirements. If maximum quality for social media is needed, we choose photo try-on with server-side GAN inference. If interactivity in the app is required, we develop real-time AR based on MediaPipe Pose. In both cases, we ensure compliance with App Store Review Guidelines and user data protection. Our experience: 5+ years in mobile development and computer vision, with over 50 completed projects for fashion brands and retailers.
In one project for a fashion brand, we implemented photo try-on with processing on an A10 GPU, allowing users to get results in 1.5 seconds. Return reduction amounted to 25%, saving up to $25,000 per month on a $100,000 turnover, and return logistics costs decreased by $1.2 per order. Average investment for such integration starts from $15,000, recouping within 3-6 months. Get a consultation to assess the effect for your business.
How does AI virtual try-on work?
We support two modes: photo try-on (user uploads a photo, result in a few seconds) and real-time AR (live camera stream with clothing overlay in real time). For photos we use heavy GAN models like HR-VITON, for AR we use a lightweight mesh approach based on MediaPipe Pose. The key phrase "virtual clothing try-on AI" applies to both modes. Our mobile try-on implementation focuses on high accuracy and low latency.
| Characteristic | Photo Try-On | Real-time AR |
|---|---|---|
| Quality | High (folds, shadows) | Medium (no folds) |
| Response time | 1-3 sec (server) | <33 ms (on-device) |
| Device support | Any with camera | iOS 12+, Android 8+ |
| Infrastructure | Server (GPU) | Client only |
Technical stack: from parsing to synthesis
On-device: MediaPipe Pose for 33 keypoints, Self-Correction Human Parsing (SCHP) for body part segmentation (converted to Core ML/TFLite). The AI clothes on photo feature uses SCHP for precise segmentation. On iPhone 13, parsing takes 300–500 ms on a 512x512 image. According to MediaPipe Pose, keypoint accuracy exceeds 95%.
// MediaPipe Pose Landmarker let options = PoseLandmarkerOptions() options.baseOptions.modelAssetPath = Bundle.main.path(forResource: "pose_landmarker_full", ofType: "task")! options.numPoses = 1 options.minPoseDetectionConfidence = 0.5 options.minPosePresenceConfidence = 0.5 options.minTrackingConfidence = 0.5 let poseLandmarker = try PoseLandmarker(options: options) let mpImage = try MPImage(uiImage: sourcePhoto) let result = try poseLandmarker.detect(image: mpImage) // Android: human parsing via TFLite val interpreter = Interpreter( FileUtil.loadMappedFile(context, "schp_parsing.tflite"), Interpreter.Options().apply { addDelegate(GpuDelegate()) } ) val input = Array(1) { Array(512) { Array(512) { FloatArray(3) } } } val output = Array(1) { Array(512) { Array(512) { FloatArray(20) } } } interpreter.run(input, output) Server-side try-on: HR-VITON — state-of-the-art model with resolution up to 1024×768. API on FastAPI + PyTorch:
@app.post("/tryon") async def virtual_tryon(person_image: UploadFile, clothing_image: UploadFile): person = load_image(await person_image.read()) clothing = load_image(await clothing_image.read()) parse_map = run_human_parsing(person) keypoints = run_pose_estimation(person) result = hrviton_model(person, clothing, parse_map, keypoints) return StreamingResponse(image_to_bytes(result), media_type="image/jpeg") Generation time on A10 GPU — 1.5–3 seconds. On CPU — 15–30 seconds.
Why is real-time AR more complex?
For real-time without heavy GAN we use mesh warping: MediaPipe Pose (30+ fps), Delaunay triangulation, texture deformation via Metal. Quality is lower, but it works on iPhone 11 without lag. Real-time AR is 30 times faster than photo try-on in response time, though it loses in detail. Performance comparison:
| Approach | FPS | Quality | Latency |
|---|---|---|---|
| Mesh warping (AR) | 30+ | Medium | <33 ms |
| GAN (photo) | <1 | High | 1.5-3 sec |
Content pipeline: each clothing item requires a photo on a white background, a silhouette mask, and a category. Auto-segmentation via RemBG, validation, upload to CDN. This clothing catalog preparation ensures consistent quality.
Data security details
All personal images are processed on the server with encryption at rest and in transit. On-device parsing does not transmit data over the network. Compliance with GDPR and App Store Review Guidelines (Section 5.1).
Implementation process: step by step
- Catalog and requirements audit — analysis of assortment, formats, target devices.
- Architecture selection — photo try-on, AR, or combination.
- On-device ML integration — install MediaPipe, Core ML/TFLite, port SCHP.
- Server inference setup — GPU inference (A10/A100) or dedicated server.
- Try-on UI development — position selection, video capture, result display.
- Testing and optimization — speed and quality measurements, stress testing.
- Deployment — app store release, CDN setup for content.
What is included in the work
- Architecture and API documentation
- Access to the source code repository
- Integration with your catalog
- Test period and 3-month support
- Team training on pipeline operation
- Deployment scripts and CI/CD configuration
These deliverables ensure smooth integration and long-term success. The on-device ML components and server infrastructure are fully documented.
Timelines and investment
Photo try-on with server inference, one platform — 4–6 weeks. Full implementation with real-time AR, both platforms, and catalog pipeline — 10–16 weeks. Cost is calculated individually — typical investment starts from $15,000 for a basic photo try-on module. Return reduction averaging 15-25% recoups the investment in 3-6 months.
