Since the mid-2000s some point and shoot cameras started to come with the feature of detecting faces for a more efficient auto-focus. The first one is the Viola-Jones framework proposed in 2001 by Paul Viola and Michael Jones in the paper Robust Real-time Object Detection. Using this transformed image result as a feature, the neural network will search for characteristics the image has in common with particular numbers. Faster R-CNN added what they called a Region Proposal Network (RPN), in an attempt to get rid of the Selective Search algorithm and make the model completely trainable end-to-end. Update log. It consists of classifying an image into one of many different categories. Satoshi Shiibashi graduated from the Tokyo Institute of Technology in 2016 with a Master’s in Information Science and Technology.
