Segment Analyser: Tool for Temporal Segmentation Research

This research tool is for evaluating temporal segmentation algorithms.

Temporal segmentation is a process of cutting sequential data into segments with different semantic meanings. Evaluation of temporal segmentation is done by comparing segments generated by an algorithm of interest with segments in a ground truth.

As final performance metrics, this tool have Perf and F1r. Perf [1] is a combination of F1-Score and Accurate Temporal Segmentation Rate (ATSR). It considers not only two typically used rates, Precision (P) and Recall (R) constituting the F1-Score, but also a frame-level precision in locating key frames.

F1r is similar to Perf, except that concordance rate (r) [2] is used instead of ATSR. This rate ensure that the output values between 0 and 1, while ATSR does not. In addition, ATSR suffers when the difference in sizes of segment between GT and Alg is large
