How effective is is? If an image is cropped by even a single row of pixels then to a computer it’s a different image is it not? It’s not likely google is doing an AI analysing of the search image against every other image on the tinterweb, that just wouldn’t be practical? |

Tin Eye searches for matching groups of pixels within an image. Of course there are ways around this too and you're never going to catch everything but it's a useful starting point |

Not sure about the technical aspects of this but crops are not an issue, sometimes even when the "main" focus is gone or a big part of the image is gone (eg. copping out a face and leaving the body); different sizes&resolution of the same pic show up also. From what I've seen I suspect hue edits may be a challenge for GIS to match up. I've also been very surprised to see that sometimes it can recognise a still taken off a video. |

"Is this the same as holding down on the image and 'search Google for image'?
Is that only for android phones - does anyone know if there is a similar ‘quick’ feature on iPhones?"
Unsure...I can't use Google image search on my android as I don't run Chrome but you could use tin eye |
