Question

how does one do a reverse image search, and how does this technology work?

In: Technology

Answer 1

Let’s look at drinks. For each drink, we’ll keep a running total of ‘points.’ If it’s hot, it gets one point. If it’s cold, it loses a point.

– Coffee is hot, +1
– Tea is hot, +1
– Milk is cold, -1

So we can see coffee and tea are more similar to one another than to milk, using this system, right?

We could make a similar system vastly more complicated, using hundreds of properties so that only a computer could check them all – color, shade, shape, texture, etc, anything you can name that makes an image unique and recognizable – to relate images to one another. You upload your image, the computer checks the image, gets the score, and then cross references that with the scores of other images – and it shows you those images under the assumption that they are similar.
