Research On Porn Videos Detection Algorithm Based On Motion Vector Statistics

Along with the network technology popularization and development, Internet has become an important part of public life.When the Internet brings convenience to us, also bring safe hidden trouble. those been naked describe of erotic, violence and other undesirable content online video and online games are poisoning people brainwashed minds and becoming the healthy growth of teenagers’information Poppy’, how to create a healthy network environment of green, clean virtual network space, cut off the network’spread and invisible pernicious hands’, become the common voice of the majority of parents、teachers and students.Aiming at the erotic video network, this paper presents a simple and fast detection algorithm, designed the corresponding detecting and filtering system.The proposed detection algorithm is calculated and normalized H.264compressed video based on motion vector.The motion vectors extracted firstly normalized calculation, and then to the dislodge hash filter and interpolation to strengthen, the motion vector field values to robust a normalized,∑MV sequence characteristics and comparison of time domain on each frame set, the trajectory and characteristics of the motion target, when the target is sensitive parts of the body motion characteristics, then to judge, and select pass or blocking-up the bit stream.
