Fast and robust video clip search using index structure
Content based retrieval of similar multimedia objects (e.g. images, text, and videos) is an important research issue in the field of multimedia database. In this demo, we present a fast and robust video clip searching system. This system consists of two major modules, namely, robust video representation and fast searching. Different from traditional key frame-based histogram methods, we employ the cumulative histogram to represent the ordinal features and color range features for a video segment. This representation provides a spatio-temporal description of the whole segment. Our experiment has shown it is effective for capturing the patterns of short video clips such as commercial, program lead in/out, flying logo in sports video, etc. In order to improve the performance in searching large video database, we introduce the index structure to deal with video search from the viewpoint of query processing (e.g. K-NN query, Range query, etc.) in high-dimensional spaces. Different query pr...
