This paper introduces a novel approach to enhance the efficiency of compressing Arabic
Unicode text using the Lempel-Ziv-Welch (LZW) technique. This method includes two …

Fractal image compression techniques are now very popular for its high compression rates
and resolution independence property. However, the qualities of decoded images of the …

In this digital era, the need of storing data has increased rapidly. This circumstance is
proportional to the size of files and their storage. In order to decrease the required big size of …

The adaptive region algorithm is an improved compression algorithm based on Huffman
coding. Because of the large number of rules for dividing regions in the algorithm, there are …

Fractal-based image coding is one of the efficient methods for grayscale image since the
reconstructed images are resolution independent and also has low reconstruction time. This …

At present, the need to access the data have been transformed into digital data, and its use
has been growing very rapidly. This transformation is due to the use of the Internet is …

The DCT-based JPEG image compression technique is a standard for lossy image
compression. But the technique is not suitable at high compression ratios. Again, it is …

In the process of using Beidou short message to communicate the message in real time,
there will be a problem of limited message length. To solve this problem, a method of …

For solving network bandwidth, and security problems, image compression, and encryption
technologies need to be combined. This paper presents two techniques for real-time …

The internet is developing rapidly, which leads to a sharp increase in security levels.
Compression of data is used to save memory securely. At the same time, the protection of …
