  • Testing Image Processing - Software Carpentry

    How do experts test image processing code? According to Steve Eddins, who writes image processing code at The MathWorks and blogged about a new testing framework for MATLAB a few days ago: Whenever there is a floating-point computation that is then quantized to produce an output image, comparing actual versus expected can be tricky.

  • Lenna - Wikipedia

    Lenna or Lena is the name given to a standard test image widely used in the field of image processing since 1973. It is a picture of the Swedish model Lena Forsén, shot by photographer Dwight Hooker, cropped from the centerfold of the November 1972 issue of Playboy magazine. The spelling "Lenna" came from the model's desire to encourage the proper pronunciation of her name.
