In the examples they show an image of a woman next to a table. The table is covered with a table cloth. In the corrupted image the table cloth looks like all noise to the human eye, however in the reconstructed image you see that the method is able to recover most of the pattern in the cloth.
- amelius 9y agoThat's something different: a demonstration of an "inpainting" problem. The black pixels were specifically marked as corrupt. Also, the pattern on the cloth is much less granular than noise.
- LoSboccacc 9y agostill the problem space is greatly reduced - all we need now is a nn to detect corrupted pixels
- amelius 9y agoWe need more than just the information where corrupted pixels are. For example, consider an image of a woman, severly blurred such that her individual fingers cannot be discerned but you can still see that it's a woman. A "learned" context-aware approach can now deduce that the "blob" that is her hand should be inpainted by fingers. A non-learned approach can't do that.
- asfdsfggtfd 9y agoBut the fingers it draws will be random fingers. Not her fingers.
- LoSboccacc 9y agotrue but it's still pretty amazing that those specific number fluctuations represent fingers (random or otherwise) without training
- rsp1984 9y agoAh, correct. Since the image was in grey I thought is was added noise, not missing pixels. Thanks for pointing that out.
