> Since the characteristic information of undesired classes of objects is all-optically erased at the camera output through light diffraction, this AI-designed camera never records their direct images. Therefore, the protection of privacy is maximized since an adversarial attack that has access to the recorded images of this camera cannot bring the information back. This feature can also reduce cameras’ data storage and transmission load since the images of undesired objects are not recorded. That seems overstated. In the third example image pair, I can easily see a shadow of the input 5 in the output. I'm pretty sure the 9 is also there in the fourth pair, but the shadow is not as clear.
