拡張機能の使用方法

Help us improve automatic porn detection by flagging images that actually aren't porn so that we can make it better!

Note: This tool is not meant to be used as a parental control or accountability software. It is easily disabled in Chrome. The goal is to gather images to improve the state of the art so that reliable porn detection can work on all devices in real time.

** Why we created this **

Porn detection with computer vision is a difficult problem with varying levels of success. Nowadays best of breed porn detection is very good at correctly identifying porn, but also recognizes many images as false positives. This can be attributed to the datasets used for training. It is easy to scrape a website for porn images and train a classifier to correctly identify those images as porn, with a sample of control images used to make sure the classifier finds particular features in the images. In the case of porn, the assumption would be that particular body parts would be the features that determine whether an image is porn or not. The problem is that if the control images are not choosen well, the features could actually be too broad and classify images as porn that aren't even closely related. For instance, the NSFW Mobile classifier currently classifies some images of rockets and bananas as porn. A reasonable observer can surmise why that's the case. We hypothesize that there are significant other types of images that result in false positives. The only way to know is to gather a dataset of the false positive images, which is what this chrome extension strives to do. Also, since this tool will be used in the wild, it will be a good proxy to build a dataset that contains a good distribution of all types of images.
