Development of a Video Content Identification Technology by NEC
NEC made an announcement on development of a video content identification technology capable of quick detection of illegal copies of video content uploaded to the internet. The detection works through generating a fingerprint (video signature) to identify video content then it compares the video signature to the original content’s signature for detecting copies or altered versions. The newly developed technology is capable of detecting altered video content such as caption overlays, camera captured copies an analog copies.
The new technology is expected to significantly reduce the amount of time and cost of manual content inspections, while improving the scale and accuracy of content assessment. The new technology is capable of extracting video signatures frame by frame based on differences in the luminance between sets of sub-regions on a frame that are defined by a variety of locations, sizes, and shapes. The new detection technology has been accepted as part of the MPEG-7 Standard.
