The Discrete Cosine Transform (DCT) is a technique used to convert signals or images from the spatial domain to the frequency domain, making it essential for applications in image and video compression. Key features include frequency representation, energy compaction, and orthogonality, which enhance compression efficiency. DCT is widely applied in JPEG and MPEG standards to reduce file sizes while preserving important information.
