The most popular search engine in China, Baidu, is reportedly working on a new image search feature for facial recognition.
Searchers can upload an image of a face and Baidu will try to return other photos of the same person, with information on the name of the person. There are reports that the feature works well with celebrities but not unknown or not-well known people.
Google does have a similar feature named Search By Image that has been around since June of 2011. Google also does have a feature in Google+ named “Find My Face” that helps users locate images of themselves.
