This paper extends the formulation of the non-linear maximum entropy (ME) technique to the continuous-target/discrete- processing/continuous-image (c/d/c) theory of insufficiently sampled images. It compares the c/d/c ME to existing discrete- input/discrete-output (d/d) ME and linear restorations. It further assesses their performance in terms of their ability to sharpen fine details of the target and suppress noise.
