Project Overview

The compresor_archivos project is a file compression and decompression tool implemented in Python. The project includes three main files: main.py, comprimir.py, and descomprimir.py. The application utilizes the Huffman coding algorithm for text, image, video, and audio file compression.

Files

main.py

This file contains the main application code, which uses the Tkinter library for the graphical user interface (GUI). The application allows users to select a file for compression or decompression and provides options for different file types. It supports compression and decompression of text, image, video, and audio files using the Huffman coding algorithm.

comprimir.py

This file includes the implementation of the file compression functionality. It defines a HuffmanTree class, which is used for Huffman coding. Additionally, there is a ColorQuantization class for quantizing colors in video files. Currently, the LZW compression code is commented out, and it can be uncommented if needed, but it is not functional yet.

descomprimir.py

This file contains the implementation of the file decompression functionality. It defines a HuffmanDecoder class, which is responsible for decoding Huffman-coded files. The descomprimir.py file mirrors the structure of comprimir.py and is designed to work with the corresponding compression logic.

Usage

To run the application, execute the main.py file. This will launch the graphical user interface where you can select files for compression or decompression.

Note: Make sure to install the necessary Python packages before running the application. You can install the required packages using the following command:

pip install bitarray opencv-python numpy

Supported File Types

The application supports the compression of the following file types:

• Text files: .txt
• Image files: .png, .jpg, .jpeg
• Video files: .mp4, .avi, .mkv
• Audio files: .mp3, .wav, .ogg

The aplication supports the descompression of the following file types:

• Text files: .crtxt
• Image files: .crpng, .crjpg, .crjpeg
• Video files: .crmp4, .cravi, .crmkv
• Audio files: .crmp3, .crwav, .crogg

The output file extensions are derived from the first two letters of my name, Cristian.

Compression Algorithm

The Huffman coding algorithm is used for file compression. It generates Huffman codes based on the frequency of characters in the input file, creating an optimal prefix-free binary tree.

Decompression

The decompression process involves decoding the compressed file using the Huffman codes generated during compression. The application supports the decompression of text, image, video, and audio files.
