Answer

Brief Explanations:

  1. Inter - frame coding: Since it stores pixel differences and can fully reconstruct the original data from those differences, it is lossless.
  2. Entropy coding: By replacing patterns with shorter representations and having a replacement table, the original data can be restored exactly, so it is lossless.
  3. Subjective field of interest: Storing less information about the background when a person is the focus means some data is discarded permanently and cannot be fully restored, so it is lossy.

Answer:

  1. Inter - frame coding: Lossless
  2. Entropy coding: Lossless
  3. Subjective field of interest: Lossy
