To reduce the storage capacity of the image, the image compression is proposed in order to offer a compact illustration of the in... ... encoder converts the image into a digital form, while...

In the decoded procedure, we plan to change the encipher picture behind one to the first simple picture in the absence of lost some dot from the primary profile [6]. AES is a detailed encode algorism make known by the US National Institute of standards and technology (NIST) in 2001.

Steganography is of 4 major types i.e. Image Steganography (Secrecy in Images), Audio Steganography (Secrecy in Audio), Video Steganography (Secrecy in video), and Text Steganography (Secrecy in Text).

Feb 1, 2019 · The method of image compression in this paper is that firstly, the image is filtered by wavelet transform to remove the redundant information in the image, and then the Huffman method is used to encode the image.

Disclosed are an image encoding and decoding method, device, equipment and system, and relate to the field of image processing technology. The encoding device encodes multiple source...

In this experiment, run length encoding (RLE), static Huffman, adaptive Huffman, Shannon Fano, arithmetic and LZW data compression algorithms were used to compress text data.

Mar 15, 2022 · Base64 encoding and decoding are when you need to encode binary data into a text format that can be easily transmitted over text-based protocols like HTTP. Node.js provides built-in methods for Base64 encoding and decoding, which can be …

This work proposes a new encoding scheme using Huffman coding for the encryption of data transmitted through a multimedia network. The proposed technique manipulates the Huffman coded...

The encoding consists of the following blocks: a prediction block; a residual data calculation block; a transformation and quantization block; an organization and modification block; and an ...
