The explosive growth of digital imaging, especially in the fields of medicine, education, and
e-commerce, has made data maintenance and transmission over networks a daunting task …

In this paper, we propose an entropy minimization histogram mergence (EMHM) scheme
that can significantly reduce the number of grayscales with nonzero pixel populations …

This paper introduces a novel lossless binary data compression scheme that is based on the
error correcting Hamming codes, namely the HCDC scheme. In this scheme, the binary …

This paper presents a new and efficient data compression algorithm, namely, the adaptive
character wordlength (ACW) algorithm, which can be used as complementary algorithm to …

Compression of images is of great interest in applications where efficiency with respect to
data storage or transmission bandwidth is sought. The rapid growth of social media and …

Image Compression is used to decrease the number of bits required to store and transmit
images without any measurable loss of information. The impact of using different lossless …

Advanced imaging technology produces a vast amount of data, particularly from the
computed tomography modality. Store the imaging data and/or transfer the data through …

In this paper we give an overview and compare Huffman and Arithmetic algorithm using
PCM audio data 16 bits stereo. The motivation for the study is to increase the transmission …
