1 – INTRODUCTION
Video retrieval: To query a database of videos whether it contains a copy of an input video clip, or possibly any similar clips. The input video may have been altered (modified or 'attacked'), and the database should still return meaningful results &ndash the system should be effective or robust. Querying should be efficient, i.e. fast, even with a large database.
Significant work has been done in the field of video retrieval to use local descriptors and various multidimensional [database indexing] methods. These have been shown to be rather effective in finding videos in large databases. The database side of things doesn't seem to be fully developed, compared with [certain indexing methods] that have proven successful in image retrieval. Furthermore, not many different kinds of video modifications have been evaluated in this type of system, modifications that [c certain type of local descriptor has been] shown to be resistant to in image retrieval.
The question is therefore whether [this combination of local descriptor and database indexing scheme is] applicable to content-based video retrieval, given that [it] has worked well in the quite similar field of image retrieval. A further question that we hope to answer is whether near-duplicate keyframe detection and removal can be used to usefully filter redundant information from videos prior to indexing and querying.

vúha. Congrats.
ég er að vísu með hita, en ég efast um að ég hafi náð að falla í stafi yfir verkefninu á viðeigandi hátt. Ég fíla "Field" það er kúl orð. Þú verður bara að blasta fegurðinni á mig síðar.
gudny
descriptors ftw both local and global
