assignTOMHT
Track-oriented multi-hypotheses tracking assignment
Description
[
returns a table of assignments,assignments
,unassignedrows
,unassignedcolumns
] = assignTOMHT(costmatrix
,costThreshold
)assignments
, of detections to tracks using a track-oriented multi-hypothesis algorithm (TOMHT).
The cost of each potential assignment is contained in the cost matrix,costmatrix
. Each matrix entry represents the cost of a possible assignments. Matrix rows represent tracks and columns represent detections. All possible assignments are represented in the cost matrix. The lower the cost, the more likely the assignment is to be made. Each track can be assigned to at most one detection and each detection can be assigned to at most one track. If the number of rows is greater than the number of columns, some tracks are unassigned. If the number of columns is greater than the number of rows, some detections are unassigned. You can set an entry ofcostmatrix
toInf
to prohibit an assignment.
costThreshold
represents the set of three gates used for assigning detections to tracks.
The function returns a list of unassigned tracks,unassignedrows
, and a list of unassigned detections,unassignedcolumns
.
