The Discrete Cosine Transform: History, Theory, and Its Impact on Image and Video Compression
Originating from three largely unknown Indian engineers in the early 1970s, the Discrete Cosine Transform (DCT) became the cornerstone of modern image and video compression standards such as JPEG and MPEG, enabling efficient lossy compression by converting spatial data to frequency components and exploiting human visual perception.
