Summary
| This is designed to assign a temporal series of visual descriptors into a video segment compactly. This can achieve image to video-frame matching and video-frames to video-frames matching functionalities. Two types of TimeSeries are available: RegularTimeSeries (with constant intervals) and IrregularTimeSeries (with various intervals). This library supports the extraction of both types and their matching (see ClientApplication as an example).

Strong Points
| High-speed video segment retrieval. Compact representation of a series of descriptors.
|
---|
Limitations
| Compare descriptions of same TimeSeries type for matching.
|
---|
Known Problems
| none
|
---|
Parameters
| TimeIncr: a default interval between descriptors.
