Tools for raster data including geophysical applications and digital elevation models

This repository contains Java code implementing the LZ-78 (Lempel-Ziv 78) data compression algorithm. The LZ-78 algorithm is a lossless data compression method that replaces repeated occurrences of data patterns with references to previously encountered patterns.

Compress image to pixels by vector quantizations

This repository contains a Java implementation of the LZ-77 data compression algorithm. LZ-77 is a lossless data compression method that replaces repetitive sequences of characters with references to previously occurring data. It achieves compression by storing the position and length of a match in a sliding window of previously processed data.

Text compression using Huffman algorithm created using java and Netbeans

Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression. It's usually implemented via a greedy approach.
