What is DCT in Image Compression Techniques about?

- The discrete cosine transform (DCT) is a technique for converting a signal into elementary frequency components. It is widely used in image compression. - The DCT transforms a list of numbers into another list where each element represents the frequency content of the original list. It is similar to the discrete Fourier transform. - The document develops simple Mathematica functions to compute the DCT and IDCT, and illustrates how the DCT can be used to compress images by removing high-frequency content
