Huffman Coding Algorithm create a priority queue Q consisting of each unique character. sort then in ascending order of their frequencies. for all the unique characters: create a newNode extract minimum value from Q and assign it to leftChild of newNode extract minimum value from Q and assign...
Huffman coding is an algorithm for compressing data with the aim of reducing its size without losing any of the details. This algorithm was developed by David Huffman. Huffman coding is typically useful for the case where data that we want to compress has frequently occurring characters in it....
In this project, have proposed discrete wavelet transform algorithm for data hiding. Thus this would provide a solution to the clone attacks and providing complete user data privacy preserving. In Huffman coding an input image is split into equal rows & columns and at final stage sum of all ...

HuffmanCoding 用Java实现的huffman编码树(仅对26个字符)。 1.使用的是26字符的频率作为各字符的权值 2.使用到最小堆,用java.util.PriorityQueue类实现。 3.各huffman node需要实现java.lang.Comparable接口 /** * HuffmanTreeNode.java */ packageHuffman;...
