Lecture: Pixel Operations and Linear Filters

Slides

View

Worksheets

Concepts

  • pixel operations / filters
  • linear / non-linear filters
  • gamma correction
  • histogram equalization
  • homogeneity
  • averaging / noise removal
  • computational kernels
  • theoretical / abstract image models
  • noise models
  • boundary conditions

Reading

  • Linearity (note that this is subtle, since it involves both real numbers and objects from some group or vector space)
  • Convolution
