NHK has accumulated a vast amount of video materials including program video and materials obtained in the course of production. The efficient use of such materials in new program production requires a way to quickly find the desired material. At STRL, we are moving forward with research on similar-image search technology for utilization of the video asset. Keyword searches are generally used to search video materials, where all video materials are tagged with text descriptions for each scene. However, this tagging requires an enormous amount of manual labor because there is considerable amount of video materials in a broadcast station. Similar-image search technology involves inputting an image at hand or obtained from the internet and searching for images that are similar to it. This technology does not need the tagging and makes it possible to easily find desired scenes.
