[Request] Find image within image

Feel free to close, but I followed along on when someone raised the image comparison suggestion and you managed to deliver that in a really pragmatic manner.

I was hoping that we as a community could find a way to do image comparison WITHIN an image. I've noticed there is a `scan` method, but I wondered if there was a way to find an image such as a logo, within a larger provided image.

I've seen python/openCV examples but nothing slick in JS.
