What technique is used by JPEGs for compression?
JPEGs use the Discrete Cosine Transform (DCT) technique for compression. DCT works by converting spatial image data into frequency domain coefficients, effectively reducing redundancy and allowing for significant compression of the image data.
C: The key to the JPEG baseline compression process is a mathematical transformation known as the Discrete Cosine Transform (DCT)
JPEGs use the Discrete Cosine Transform (DCT) technique for compression. This mathematical transformation converts spatial image data into frequency domain coefficients, reducing redundancy and achieving compression.
