IQ Engines uses computer vision for object recognition, but we resort to human crowdsourcing (image tagging) if computer vision is not successful. We built our crowdsourcing network and techniques to optimize speed and performance. In the most simple sense, IQ Engines crowdsourcing is humans doing object recognition. It’s not perfect, but we think human crowdsourcing will get better soon, with “expert tagging” and “social tagging” projects in the pipeline, that will result in more detailed and accurate tags.

One special feature IQ Engines offers is a “custom question” for API users that rely on crowdsourcing. That means, along with the mobile photo, a custom question is sent to the human crowd to answer about the photo. This can improve your tagging results.

Note: You can configure your API key to use only computer vision if needed.
