Swift_NSFW_Detector

An NSFW image detector for Swift built as an extension on UIImage.

If you've ever allowed users to share images you are probably wishing you had implemented a 'hotdog' filter. Now you can easily filter images when they are selected or before they are shared.

The MLModel used in this implementation is Yahoo's OpenNSFW.mlmodel

Based on https://github.com/kashif/NsfwDetector this extension makes implementation much simpler.

Installation

Copy NSFWDetector.swift and OpenNSFW.mlmodel into your project and you're done.

Sample usage:

let image = UIImage(...)
image.checkNSFW() { result, confidence in
  switch result {
    case .sfw:
      self.allowImage()
    case .nsfw:
      if conficence > 0.5 {
        self.blockImage()
      } else {
        self.allowImage()
      }
    case .unknown:
      self.flagImage()
  }
}
