# Image Enhancement Guide

Improve image quality for documentation, presentations, and social media.

## When to Use

- Improving screenshot quality for blog posts
- Enhancing images for social media
- Preparing images for presentations
- Upscaling low-resolution images
- Sharpening blurry photos
- Cleaning up compressed images

## Enhancement Workflow

1. **Analyze** - Check resolution, sharpness, artifacts
2. **Enhance** - Apply appropriate improvements
3. **Optimize** - Adjust for intended use case
4. **Save** - Preserve original, save enhanced version

## Python Enhancement Script

```python
from PIL import Image, ImageEnhance, ImageFilter

def enhance_image(input_path, output_path):
    img = Image.open(input_path)

    # Upscale if small
    if img.width < 1920:
        scale = 1920 / img.width
        new_size = (int(img.width * scale), int(img.height * scale))
        img = img.resize(new_size, Image.LANCZOS)

    # Sharpen
    img = img.filter(ImageFilter.SHARPEN)

    # Enhance contrast slightly
    enhancer = ImageEnhance.Contrast(img)
    img = enhancer.enhance(1.1)

    img.save(output_path, quality=95)
    return img.size

# Usage
enhance_image('screenshot.png', 'screenshot-enhanced.png')
```

## ImageMagick Commands

```bash
# Sharpen image
convert input.png -sharpen 0x1 output.png

# Upscale 2x with good quality
convert input.png -resize 200% -filter Lanczos output.png

# Remove compression artifacts
convert input.jpg -enhance output.jpg

# Batch process folder
for f in *.png; do
    convert "$f" -sharpen 0x1 "enhanced-$f"
done
```

## Optimization by Use Case

| Use Case | Resolution | Format | Quality |
|----------|------------|--------|---------|
| Web/Blog | 1920px wide | PNG/WebP | 85-95% |
| Social Media | Platform-specific | JPG | 90% |
| Presentations | 2560px+ | PNG | 95% |
| Print | 300 DPI minimum | PNG/TIFF | 100% |

## Social Media Sizes

| Platform | Recommended Size |
|----------|-----------------|
| Twitter | 1200x675 |
| LinkedIn | 1200x627 |
| Instagram | 1080x1080 |
| Facebook | 1200x630 |

## Tips

- Always keep original files as backup
- PNG for screenshots (lossless)
- JPG for photos (smaller size)
- WebP for web (best compression)
- Batch process for multiple files

## Required Tools

```bash
# Python
pip install Pillow

# ImageMagick
sudo apt-get install imagemagick

# For advanced upscaling
pip install opencv-python
```

physical-ai-defect-image-generation

Included

Use when the user wants to orchestrate defect image generation, run associated setup, or handle outputs on OSMO. The Day 0 path handles cold-start with USD-to-ROI, image-edit augmentation, and AnomalyGen to create initial PCBA datasets. The Day 1 path performs inference and labeling on real images. This skill helps with first-time asset setup, creation of finetuning checkpoints, and configuring deployment.

accelint-react-best-practices

Included

React performance optimization and best practices. ALWAYS use this skill when working with any React code - writing components, hooks, JSX; refactoring; optimizing re-renders, memoization, state management; reviewing for performance; fixing hydration mismatches; debugging infinite re-renders, stale closures, input focus loss, animations restarting; preventing remounting; implementing transitions, lazy initialization, effect dependencies. Even simple React tasks benefit from these patterns. Covers React 19+ (useEffectEvent, Activity, ref props). Triggers - useEffect, useState, useMemo, useCallback, memo, inline components, nested components, components inside components, re-render, performance, hydration, SSR, Next.js, useDeferredValue, combined hooks.

humanizer

Included

Humanize AI-generated text by detecting and removing patterns typical of LLM output. Rewrites text to sound natural, specific, and human. Uses 28 pattern detectors, 560+ AI vocabulary terms across 3 tiers, and statistical analysis (burstiness, type-token ratio, readability) for comprehensive detection. Use when asked to humanize text, de-AI writing, make content sound more natural/human, review writing for AI patterns, score text for AI detection, or improve AI-generated drafts. Covers content, language, style, communication, and filler categories.

generating-mermaid-diagrams

Included

Salesforce architecture diagrams using Mermaid with ASCII fallback. Use this skill when generating text-based diagrams for Salesforce architecture, OAuth flows, ERDs, integration sequences, or Agentforce structure. TRIGGER when: user says "diagram", "visualize", "ERD", or asks for sequence diagrams, flowcharts, class diagrams, or architecture visualizations in Mermaid.
