Firstly, the algorithm codifies the secondary DNA key which is extracted from the main DNA key according to Huffman coding. Then an XOR is applied between the coded DNA sequence and the plain-image. And in order to strengthen our algorithm, we have performed diffusion with a permutation box....
Using the Huffman Coding technique, we can compress the string to a smaller size. Huffman coding first creates a tree using the frequencies of the character and then generates code for each character. Once the data is encoded, it has to be decoded. Decoding is done using the same tree. Hu...
This article contains basic concept of Huffman coding with their algorithm, example of Huffman coding and time complexity of a Huffman coding is also prescribed in this article.
16.2 -Elements of the greedy strategy - same as 16.1 16.3 -Huffman codes - I'd say read the problem and the algorithm, but that's enough. I've seen interview questions where the answer is Huffman coding (but the question will come up in a 'disguised form', so it won't be obvious...

Huffman code is a type of optimal prefix code that is commonly used for lossless data compression. The algorithm has been developed by David A. Huffman. The technique works by creating a binary tree of nodes. Nodes count depends on the number of symbols.
A quasi-lossless compression algorithm for location information within civilian global positioning system (GPS) was proposed based on the analysis and comparison of performance between Huffman coding and arithmetic coding thus improving location data compression ratio and compression speed within civilian GPS...
Working of Huffman Coding:Huffman coding works by creating a binary tree of nodes. These nodes represent the frequency of each character. The algorithm builds the tree from the bottom up, starting with the least frequent characters. At each step, it selects two nodes with the lowest ...
