I wonder if the &quot;deep learning&quot; is getting any hints from the bayer patterns that may be detectable even in the desaturated image. It would be interesting to see what it did from a true b&#x2F;w sensor, a Fovean sensor, or a scan of black and white films.<p>On a related &quot;deep learning&quot; topic:<p>We do a lot of work with 3D modeling tools and scanning large objects, including people, at our facility.<p>One thing we realized that should be possible with &quot;deep learning&quot; is taking a standard human computer model, and configuring it to match the position and shape of a scanned human model, or a photo of a human being -- in order to add back missing bits. Imagine a website where you can upload a swimsuit image and get back a computer generated nude image with the obscured body parts replaced. This should be very doable today, and would make a very popular website!
