Week 02 – Biometric Generation & Facial Editing
Dates: 2025-06-01 – 2025-06-07
Internship: AI/ML Intern at SynerSense Pvt. Ltd.
Mentor: Praveen Kulkarni Sir
Focus
This week involved exploring ComfyUI and other tools to synthetically generate facial biometric data, modify features using inpainting, and experiment with scar overlays.
Goals for the Week
- Generate fake biometric images using ComfyUI
- Add synthetic features (black line, scar) to facial images
- Explore alternative generation tools: InvokeAI, Automatic1111, Replicate
- Create human-like facial outputs with node workflows and prompt tuning
Tasks Completed
| Task | Status | Notes |
|---|---|---|
| Generated biometric-style face (no specs, neutral pose) using ComfyUI | ✅ Completed | Used prompts with facial constraints |
| Added black line to face image programmatically | ✅ Completed | Used Python & OpenCV |
| Designed prompt to replace black line with a scar | ✅ Completed | Implemented via Stable Diffusion inpainting |
| Explored and compared generation tools (ComfyUI, InvokeAI, etc.) | ✅ Completed | Identified potential of each tool for future workflows |
| Built workflow to enhance facial details using nodes in ComfyUI | ✅ Completed | Achieved realistic results through graph-based pipeline |
Key Learnings
- ComfyUI workflows can be fine-tuned for biometric and facial realism
- Stable Diffusion inpainting + ControlNet enables creative control
- Multiple tools offer trade-offs: use what fits the goal & complexity
- Consistency in output quality can be handled by systemized pipelines
Problems Faced & Solutions
| Problem | Solution |
|---|---|
| Lack of realism in generated faces | Switched models, explored more humanistic face generation |
| Workflow getting too reliant on one tool | Expanded exploration to InvokeAI, A1111, Replicate |
| Prompt not giving desired scar effect | Tweaked prompts and used ControlNet with mask editing in ComfyUI |
| Unclear consistency between runs | Discussed with mentor about future integration with AI stack team |

Goals for Next Week
- Implement Hugging Face login flow with Gradio
- Show user identity after Google login
- Fix environment issues in Spaces (Python version, OAuth vars)
Screenshots (Optional)
Add before/after images, mask editor view, scar rendering outputs
“This week taught me that tool flexibility matters as much as skill depth—great workflows come from trying, tweaking, and switching when needed.”
