Google goggles is the latest android application designed to search stuffs on the internet by PHOTO. Now one can upload photo to application and then it will find related profiles and other links on the internet. I want to know that which mechanism they are using behind that ?
Firstly, I think about color intensity but it might not work..then I think about shape distribution to x axis and y axis with color intensity but i think its not correct.
Now can anyone tell me that which technology they are using in back end ?
