Compressive sensing (CS) works to acquire measurements at sub-Nyquist rate
and recover the scene images. Existing CS methods always recover the scene
images in pixel level. This causes the smoothness of recovered images and lack
of structure information, especially at a low measurement rate. To overcome
this drawback, in this paper, we propose perceptual CS to obtain high-level
structured recovery. Our task no longer focuses on pixel level. Instead, we
work to make a better visual effect. In detail, we employ perceptual loss,
defined on feature level, to enhance the structure information of the recovered
images. Experiments show that our method achieves better visual results with
stronger structure information than existing CS methods at the same measurement
rate.Comment: Accepted by The First Chinese Conference on Pattern Recognition and
