Nudity-detection as a service is the result of a 10% project at Haschek Solutions. It uses Raspberry Pis and Intel NCS (Neural Compute Sticks) to classify images as porn or not porn.
Sysadmins can use the API to find illegal or unwanted uploads on their webservices. NaaS already helped find uploaders of child pornography to various image hosters.
PictShare was born out of the need for more control over the images we used in our projects, blogs and eBay pages. Host your own PictShare instance and you'll never have to trust a shady free image hoster again.
