Query: On The Classification-Distortion-Perception Tradeoff   Signal degradation is ubiquitous and computational restoration of degraded
signal has been investigated for many years. Recently, it is reported that the
capability of signal restoration is fundamentally limited by the
perception-distortion tradeoff, i.e. the distortion and the perceptual
difference between the restored signal and the ideal `original' signal cannot
be made both minimal simultaneously. Distortion corresponds to signal fidelity
and perceptual difference corresponds to perceptual naturalness, both of which
are important metrics in practice. Besides, there is another dimension worthy
of consideration, namely the semantic quality or the utility for recognition
purpose, of the restored signal. In this paper, we extend the previous
perception-distortion tradeoff to the case of
classification-distortion-perception (CDP) tradeoff, where we introduced the
classification error rate of the restored signal in addition to distortion and
perceptual difference. Two versions of the CDP tradeoff are considered, one
using a predefined classifier and the other dealing with the optimal classifier
for the restored signal. For both versions, we can rigorously prove the
existence of the CDP tradeoff, i.e. the distortion, perceptual difference, and
classification error rate cannot be made all minimal simultaneously. Our
findings can be useful especially for computer vision researches where some
low-level vision tasks (signal restoration) serve for high-level vision tasks
(visual understanding).
