Google -- Image recognition

Image recognition has been the research of interest in the field of AI since long ago. and surprisingly,a minute ago I've only found out that Google has actually came out with this application, images.google.com.



Incredibly user friendly, where we only need to drag and drop the image of interest to the search box and it will automatically google for you.



and here's the output, at which the image is successfully found, provided the link of the exact image in the WWW.



But what happen if a random image is fed?





From the obtained results, my first visual conceptual conclusion is that the searching algorithm considers only the colors of the image. So to prove me wrong, another simpler image is tested.

and to my surprise, this is the outcome when the star is fed. It manage to find Australia where the national flag contains the six-pointed star.



Thus, Shape is also being taken care of in the algorithm. So what else...

Object's texture??

Yea, may try that out, but not now :D

Anyway, certainly am very impressed with GOOGLE.
