An artist’s impression of a quantum electrodynamics simulation using 100 qubits of an IBM quantum computer. The spheres and lines denote the qubits and connectivity of the IBM quantum processor; gold ...

LinkedIn support accidentally revealed its algorithm: it tracks "viewer tolerance," reducing visibility for authors whose posts are consistently ignored. To succeed, diversify content types weekly, ...

Cryptography secures communication in banking, messaging, and blockchain. Good algorithms (AES, RSA, ECC, SHA-2/3, ChaCha20) are secure, efficient, and widely trusted. Bad algorithms (DES, MD5, SHA-1, ...

The discrete cosine transform (DCT) remains a cornerstone of modern image and video compression techniques, enabling the decomposition of visual data into frequency components that can be efficiently ...

Abstract: In traditional three-dimensional (3D) discrete cosine transform (DCT) algorithm, three dimensions are processed separately. In order to realize 3D global DCT and construct the unity ...

Abstract: This paper proposes the steganography algorithm based on ±1 coefficients after discrete cosine transform (±1 DCT) for H.264/AVC. The ±1 DCT algorithm embeds information bits differently on ...
