System Requirements Document (SRD) for sweet-hug

1. Introduction

The sweet-hug project is a heartfelt initiative by Nahla Alrabkhi, based in Oman, aimed at creating a natural and emotional family photo of two women hugging warmly. The project emphasizes preserving the original facial features of the women in the source photos while ensuring the final image looks realistic and evokes genuine emotion.

2. System Overview

The sweet-hug system will utilize advanced photo editing and compositing techniques, supported by AI-powered tools, to generate a realistic family photo. The system will focus on:

• Seamlessly merging the two women's images into a single composition.
• Retaining the original facial features without distortion.
• Creating a warm, natural, and emotional atmosphere in the final output.
• Ensuring the final image adheres to the cultural and aesthetic preferences of Oman.
• Supporting the generation of realistic family photos featuring two women hugging, using face preservation from uploaded reference photos.

3. Functional Requirements as Story Points

• As a User, I should be able to upload two photos of individuals to be merged into a single image.
• As a User, I should be able to specify that the original facial features of the individuals must remain unchanged.
• As a User, I should be able to preview the final composite image before downloading.
• As a User, I should be able to download the final image in high resolution.
• As a User, I should be able to apply optional filters or enhancements to the final image for a more polished look.
• As a User, I should be able to generate a realistic family photo featuring two women hugging, with their original faces preserved.

5. Visuals Colors and Theme

The sweet-hug project will use a warm and inviting color palette to evoke feelings of love and family. The colors are inspired by the cultural and aesthetic preferences of Oman.

6. Signature Design Concept

The sweet-hug homepage will feature an interactive photo frame concept. The landing page will display a virtual photo frame with a soft, glowing border. Users can drag and drop their images into the frame, and the system will animate the merging process in real-time.

Key Features:

• Dynamic Animation: As users upload photos, the frame will "light up" with a warm glow, symbolizing connection and love.
• Real-Time Preview: The photo frame will display a live preview of the composite image being created.
• Cultural Motifs: Subtle Omani-inspired floral patterns will appear around the frame, adding a touch of local identity.
• Micro-Interactions: Hovering over the frame will trigger soft animations, such as a gentle shimmer or a heartbeat effect.

This design ensures the project leaves a lasting impression while aligning with its emotional and cultural goals.

7. Non-Functional Requirements

• The system must process images within 10 seconds for a seamless user experience.
• The final image resolution must be at least 300 DPI for high-quality prints.
• The system must ensure data privacy and not store user-uploaded images beyond the session.

8. Tech Stack

Frontend

• React for Web

Backend

• Python
• FastAPI

Database

• MySQL (for storing user preferences and session data)

AI Models

• Google Nano Banana (for image generation and enhancement)

AI Tools

• Langchain (for workflow orchestration)

Local Orchestration

• Docker
• docker-compose

Server-Side Orchestration

• Kubernetes

9. Assumptions and Constraints

• The system assumes users will upload high-quality images for optimal results.
• The system is constrained by the need to preserve original facial features, limiting the extent of automated adjustments.
• The project will adhere to cultural sensitivities and avoid any alterations that may be deemed inappropriate.

10. Glossary

• Composite Image: A single image created by merging two or more separate images.
• DPI: Dots Per Inch, a measure of image resolution.
• Micro-Interactions: Small animations or design elements that enhance user experience.
• Omani-Inspired Motifs: Design elements reflecting the cultural aesthetics of Oman.
