What are some takeaways after reading this?

  • Computers see images as matrices of numbers
  • An image is described as a 2 dimensional matrix of pixel values
  • Each pixel represents color values
  • Distance between images is sum of difference of pixels

$$d_1 (I_1, I_2) = \sum_{p} \left| I^p_1 - I^p_2 \right| $$
