What is OpenCV?

Open Source Computer Vision Library: A Python library used for everything from basic image processing to Tensor Flow Computer Vision.

Uses

• Basic image processing
  • Crop
  • Adjust
  • Rotate
  • Denoise
  • Skew
• Computer Vision
• Edge detection
• Background subtraction
  • Static background vs moving foreground
• Colour Quantization
  • Reduces unique colours using K-Means clustering
• Fixing exposure
  • Uses histograms of all the pixels in the image
  • 0 completely black pixels
  • 255 completely white pixels
  • Poorly exposed/contrasted images statistically ironed out
