Leveraging the power of machine learning, image recognition APIs have become a powerful resource for system developers. There are a number of product offerings from IBM, Google, Amazon, Microsoft, and others. This talk compares and contrasts the APIs, performance, and most importantly, the accuracy of leading image recognition APIs. The APIs are not created equal and they don't perform equally. Some of the vendors excel at specific problems and struggle with others. This talk leverages several months of research and testing we performed to help you figure out which vendors may be best suited for your problem space.
