Basic Concept of Image Processing

  • Convolution between image and filter(kernel)
  • Each processing of pixel independent from another pixels
  • Can be used for Edge finding, Blur and image enhancement.
Examples of Image Processing

Convolution for image and filter

filters

Edge Handling

All pixels in edges needs special calculation.

  • Extend
  • Tile
  • Crop
