Image Enhancement Skill
Improve image quality through upscaling, denoising, sharpening, and color correction.
When to Use
- Low-resolution images
- Noisy/grainy photos
- Poor lighting correction
- Professional photo editing
Core Capabilities
- AI upscaling (2x, 4x, 8x)
- Noise reduction
- Sharpening
- Color correction
- Contrast/brightness adjustment
- HDR enhancement
Tools
# ImageMagick
convert input.jpg -sharpen 0x1 -enhance output.jpg
# waifu2x (AI upscaling)
waifu2x-ncnn-vulkan -i input.jpg -o output.png -s 2
# Topaz Gigapixel AI
# Real-ESRGAN
realesrgan-ncnn-vulkan -i input.jpg -o output.jpg -s 4
Python (OpenCV)
import cv2
img = cv2.imread('input.jpg')
enhanced = cv2.detailEnhance(img, sigma_s=10, sigma_r=0.15)
cv2.imwrite('output.jpg', enhanced)
Best Practices
- Start with highest quality source
- Use AI upscaling for photos
- Adjust settings iteratively
- Compare before/after
- Batch process similar images
