Two-Dimensional Vector Quantization Animation
  • If the animation appears to be stuck, try moving up or down the page in your browser.
  • The source for the above is a memoryless Gaussian source with zero-mean and unit variance.
  • The tiny green dots are training vectors --- there are 4096 of them.
  • The LBG design algorithm is run with .
  • The algorithm guarantees a locally optimal solution.
  • The size of the training sequence should be sufficiently large. It is recommended that the number of training vectors should be 1000 times the number of codevectors.
