Discrete Cosine Transform (DCT)
JPEG is an acronym for Joint Photographic Experts Group. It refers to a definition of a still-image compression algorithm established by the JPEG committee. JPEG works best on continuous tone images such as grayscale and color. A DCT-based (Discrete Cosine Transform) method is specified for lossy compression algorithm.
