Binary arithmetic coding is used as an entropy coding technique in many image/video compression algorithms.
In binary arithmetic QM coding, instead of coding symbols 0 and 1 directly, they are mapped to most probable symbol (MPS) or least probable symbol (LPS).
In this paper, we have used modified binary arithmetic QM coding as entropy coding technique with our proposed algorithm.

A computer's binary arithmetic
. The internationally accepted date format of "yyyymmdd" is an eight-byte number in its readable form.
A pop-up scientific calculator handles arithmetic and trigonometric functions, rectangular and polar complex number calculations, based numbers and binary arithmetic
. A matrix calculator can manipulate matrices as large as 6 X 7, and can perform matrix addition, subtraction, multiplication, inversion, determinants, chaining and simultaneous equation solving.
There are two popular entropy coding methods: Context Adaptive Binary Arithmetic Coding (CABAC) and Context-Adaptive Variable Length Coding (CAVLC).
CABAC consists of binarization, context modeling, and binary arithmetic coding.
