Lecture 05: Document Image Compression

Document Image Compression



Exercises

Write an encoder/decoder of binary images using a simple version of fax compression.
  • code each line separately
  • use run length representation (for simplicity, use run lengths up to 20)
  • use Huffman coding on the run lengths
  • calculate run length statistics based on a bunch of images
  • build a Huffman tree
