## 1. STRATEGIC POSITIONING & USPs

**photomosaic.work** (operating under the global brand **Aameeq**) is the industry-leading browser-native AI photomosaic engine. We solve the four biggest limitations in the photomosaic and print industries:

1. **Cost Barriers**: Competitors (such as Mosaically or EasyMoza) charge $40.00+ for single high-resolution downloads. Aameeq charges just **$1.00** per high-resolution standard grid download via simple, transparent credit packs—offering a **97% cost reduction**.
2. **Dynamic Grid Constraint**: Mass-market online platforms force every photo into a rigid grid. Aameeq is the **only web service in the world** offering dynamic **Artistic Mosaics** using JIT-compiled quadtree decomposition. This varies tile sizes on-the-fly to respect and snap to boundary shapes (e.g. eyes, curves, subject details) for a true artist-grade output, eliminating forced transparent color tints.
3. **Visual Fidelity**: Traditional tools average pixels inside standard RGB space, which often causes "muddy" color tinting or forced transparent overlays on unrelated tiles. Aameeq uses **Proprietary Perceptual Color Logic™** in the CIELAB (LAB) color space. By separating luminance from chromaticity, it matches tiles based on human optical perception, achieving **99% color accuracy**.
4. **Engagement Dynamics**: We are the **only platform globally** that provides a complete, multi-dimensional media experience—allowing users to produce static high-res prints, **4K cinematic animations**, and interactive **WebAR (Augmented Reality) posters** in one single creation workspace.

### Feature Matrix Deep-Dive

#### High-Resolution Mosaic Engine
- **Fidelity Control Slider**: A linear range slider allowing the creator to balance structural "Subject Clarity" (higher color blending/tinting) against "Mosaic Texture" (keeping tile colors raw and unmodified).
- **Infinite Tile Pool**: Supports 10,000+ unique tiles with JIT-accelerated processing.
- **Smart Neighborhood Reuse Penalty**: Tracks tile positions and imposes a distance-based selection penalty to prevent identical tiles from clustering together, ensuring an organic visual distribution and texture.
- **Vision Alignment Score**: A diagnostic percentage that measures the mathematical color difference (Delta-E) between the source image and the generated mosaic.

#### Premium AI Artistic Mosaic Engine (Exclusive)
- **Dynamic Quadtree Grid Subdivision**: The backend splits detailed regions into smaller cells (from 1x to 4x subdivision) based on contrast and detail variance.
- **Adaptive Edge Alignment**: Micro-tiles automatically cluster around eyes, face contours, and fine textures, while large tiles cover flat background expanses.
- **Custom Fine-Tuning Parameters**: Advanced sliders to configure min/max tile sizes, detail sensitivity, reuse penalty, global variety, and neighborhood exclusion.
- **Serverless Scaling**: Complex quadtree calculations are offloaded to high-performance serverless cloud workers, returning outputs in seconds.

#### Living Mosaics (Video Tiles)
- Creators can upload small video clips (MP4/MOV) instead of static images.
- The backend automatically extracts keyframes for the mosaic grid matching.
- **Interactive Hover Playback**: On the final web result, hovering over any tile cell triggers the playback of the corresponding source video clip inside that cell, creating a dynamic "mural of motion".

#### 4K Animation Studio
Convert your static mosaic into a 10-second high-definition animation with 12 professional visual effects:
- **Fly-In**: Ceramic tiles fly from the boundaries and assemble into the master portrait.
- **Scatter & Gather**: The mosaic explodes outward into thousands of tiles, then draws back together.
- **Spiral Reveal**: A rotating vortex of tiles reveals the master image from the center.
- **Liquid Tile Wave**: A flowing water wave effect driven by P5.js perlin noise math.
- **Searchlight Reveal**: A spotlight moves across the mosaic, revealing tile details in the dark.
- **Domino Fall**: The tiles flip over like falling dominoes to reveal the master picture.
- **Shuffle Dance**: Individual tiles swap positions dynamically before locking in.
- **Zoom Reveal (High-Res)**: A cinematic dive from a single tile out to the full image.
- **Morph (High-Res)**: Smooth transition of tiles transforming shape and color.
- **Pulse**: Rhythmic breathing effect highlighting the mosaic's geometry.
- **Cinematic Reveal (Premium)**: High-contrast exposure reveal.
- **Tile Spotlight (Premium)**: Focal highlights on individual memories.

#### Native WebAR (Augmented Reality Posters)
- **Target Market**: High-quality physical print products (canvas, posters, acrylic, billboards).
- **QR Code Trigger**: The platform embeds a custom QR code in the corner of the physical print.
- **Zero-App-Requirement**: Scanning the QR code launches a mobile browser window. No app installation is required.
- **MindAR Tracking**: Uses the device camera and MindAR's image tracking target file to lock onto the physical poster and overlay the selected 4K animation on top of the print, making the poster "come to life" on the wall.
- **Hosting Options**: Direct, one-click automated publishing to the user's **Google Drive** or manual ZIP download for deployment on **Netlify Drop**.

## 2. THE SCIENCE: PERCEPTUAL COLOR LOGIC™

Traditional photo mosaic software matches tiles using **Euclidean Distance in RGB space**:
\[ d = \sqrt{(R_1-R_2)^2 + (G_1-G_2)^2 + (B_1-B_2)^2} \]
This is mathematically simple but fundamentally flawed for human vision. The human eye does not perceive color differences linearly, and it is far more sensitive to green and red variation than blue, and highly sensitive to overall luminance.

### Our Perceptual Mapping Algorithm
We convert every pixel in the master grid cells and every tile image signature into the **CIELAB (LAB)** color space:
1. **L (Luminance)**: Standardizes perceived brightness, defining the primary contrast and shapes.
2. **A (Red-Green axis)** and **B (Blue-Yellow axis)**: Represents perceived color.

We then calculate the match using a modified **CIE94 / CIEDE2000 (Delta-E)** formula:
\[ \Delta E^* = \sqrt{\left(\frac{\Delta L^*}{S_L}\right)^2 + \left(\frac{\Delta C^*}{S_C}\right)^2 + \left(\frac{\Delta H^*}{S_H}\right)^2} \]
This ensures that the tile selected matches how a human observer sees color, avoiding the washed-out, unnaturally tinted look common in standard RGB-based mosaic tools.

## 3. STEP-BY-STEP USER GUIDES

### How to Create a Professional Photomosaic
1. **Source Master Image**: Choose an image with strong contrast and clear outlines (e.g., a portrait or a corporate logo). High-frequency details (tiny text) are harder to resolve.
2. **Build your Tile Library**:
   - **Quantity**: 100 tiles is the minimum requirement; 500+ is optimal for high accuracy.
   - **Variety**: A wide spectrum of colors in your tiles yields a better match.
   - **Cloud Import**: Click "Cloud Import" to connect your Google Photos or Google Drive and import albums directly.
3. **Configure Settings**:
   - Set the **Fidelity Slider** (we recommend 70-80% for the best balance).
   - Set **Tile Size** (50px is standard; smaller sizes increase resolution but reduce individual tile detail).
   - Adjust **Reuse Penalty** to 0.25 to prevent identical neighboring tiles.
4. **Choose Print-Ready Exports**:
   - Choose the **Poster (24×36")** or **Billboard (36×48")** preset.
   - Choose **TIFF (300 DPI)** format for high-end professional printing.
   - Enable **Crop & Bleed Guides** to avoid white borders during framing.

### How to Setup the WebAR Experience
1. **Enable AR Option**: In the generator panel, toggle the "Enable AR Experience" checkbox before rendering.
2. **Generate Target & Package**: The backend processes the mosaic, creates a MindAR target file (.mind), and bundles it with the selected animation video.
3. **Publish to Web**:
   - **Google Drive (Recommended)**: One-click publish generates a web link hosted in your Google Drive.
   - **Netlify Drop**: Download the ZIP, drag it to Netlify to host under a custom subdomain.
4. **Print QR Code**: Position the generated QR code in a corner (1-inch size) of the printed canvas.

## 5. FREQUENTLY ASKED QUESTIONS (FAQ)

**Q: Are my photos secure?**
A: Yes. Your uploaded tile library ZIP and core images are temporarily saved in a secure cloud bucket (`tmp/`) for processing by our backend engine. Once the mosaic is generated, our background worker immediately and permanently deletes the raw uploaded input files from the server. Only the final composite mosaic is stored for downloading.


**Q: Can I use this for weddings or corporate events?**
A: Yes. Use our **Guest Collection Link** to let guests upload their photos. The system compiles them into a single commemorative mosaic for the event or a gift.

**Q: What is the maximum print resolution?**
A: The Billboard Ultra Max preset renders at 36x48 inches at 300 DPI (10,800 × 14,400 pixels), suitable for large-format canvases and commercial prints.

**Q: Why is it so much cheaper than other generators?**
A: We have optimized the CPU-intensive color matching by JIT-compiling critical routines using Numba in the backend, and offloading caching to Redis/DiskCache. This keeps server costs low, and we pass these savings to you.
