Activity Recognition based on a Magnitude-Orientation Stream Network
The temporal component of videos provides an important clue for activity recognition, as a number of activities can be reliably recognized based on the motion information.
A Mid-level Video Representation based on Binary Descriptors: A Case Study for Pornography Detection
Although these approaches provide good results, they generally have the disadvantage of a high false positive rate since not all images with large areas of skin exposure are necessarily pornographic images, such as people wearing swimsuits or images related to sports.
