JPEG encoding involves ___, a process that reveals the redundancies in a block.

B) the discrete cosine transform
C) quantization
D) vectorization

Question

Quizplus · Accepted Answer

JPEG encoding involves the discrete cosine transform (DCT), which transforms the image from the spatial domain to the frequency domain, revealing the redundancies in a block. This is followed by quantization, which reduces the precision of the DCT coefficients in a lossy manner. Blocking and vectorization are also part of the JPEG encoding process, but they do not directly involve revealing redundancies in a block.
