Utilities¶

Functions to handle event lists (list of event items), event rolls (event activity indicator matrix used in evaluation), and scene lists.

Event list operations¶

`event_list.unique_event_labels`(event_list)	Find the unique event labels
`event_list.unique_files`(event_list)	Find the unique files
`event_list.filter_event_list`(event_list[, ...])	Filter event list based on given fields
`event_list.max_event_offset`(event_list)	Find the offset (end-time) of last event

`event_roll.event_list_to_event_roll`(...[, ...])	Convert event list into event roll, binary activity matrix
`event_roll.pad_event_roll`(event_roll, length)	Pad event roll’s length to given length
`event_roll.match_event_roll_lengths`(...[, ...])	Fix the length of two event rolls

scene_list.unique_scene_labels(scene_list) Find the unique scene labels

event_matching.bipartite_match(graph) Find maximum cardinality matching of a bipartite graph (U,V,E).
