Image-Compression

Authors

  • Bruno Flávio Ferreira
  • Edson Yudi Toma

Main Objective

The project aims to compress an image using Fourrier Transform and Huffman Compression.

Input Images

The input images can be any uncompressed image, we use in this project the "Standard" test images, an .tif image database located at http://imageprocessingplace.com/root_files_V3/image_databases.htm to test the algorithm

The images can be colored or not:

Algorithm Steps (Compression)

  • Read uncompressed image
  • Apply FFT in the image
  • Cut of values below an given threashold
  • Apply Huffman compression in the FFT image
  • Save the compressed image

ALgorithm Steps (Decompression)

  • Read compressed image
  • Apply Huffman decompression
  • Aplly the Inverse FFT in the decompressed image
  • Show the image in the screen
