Claim 0:
1. An apparatus for online action detection, the apparatus comprising:
a feature extraction unit configured to extract a chunk-level feature of a video chunk sequence of a streaming video;
a filtering unit configured to perform filtering on the chunk-level features; and
an action classification unit configured to classify an action class using the filtered chunk-level features, wherein
the filtering unit configured to receive a chunk-level feature sequence and infer a relation of an action instance represented by a current chunk and other chunks to generate a filtered chunk-level feature sequence to be used for action classification, and
the filtering unit configured to predict an action relevance of each chunk with the current point in time so as to generate filtered features in which a feature of a chunk related to the current point in time is emphasized and a feature of a chunk unrelated to the current point in time is filtered out.
