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

# 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"

# Python
pip install Pillow

# ImageMagick
sudo apt-get install imagemagick

# For advanced upscaling
pip install opencv-python
