I am getting this error "Undefined function 'assignDet​ectionsToT​racks' for input arguments of type 'double'." . So is the function not there in CV toolbox 5.0? If so what is a similar function available that I can use

I'm trying to use this function from multiple objects tracking code in MATLAB, but I'm having trouble since it depends on assignDetectionsToTracks function which I cannot find in my toolbox

function [assignments, unassignedTracks, unassignedDetections] = ... detectionToTrackAssignment()

        nTracks = length(tracks);
        nDetections = size(centroids, 1);

        % Compute the cost of assigning each detection to each track.
        cost = zeros(nTracks, nDetections);
        for i = 1:nTracks
            cost(i, :) = distance(tracks(i).kalmanFilter, centroids);
        end

        % Solve the assignment problem.
        costOfNonAssignment = 20;
        [assignments, unassignedTracks, unassignedDetections] = ...
            assignDetectionsToTracks(cost, costOfNonAssignment);
    end

Jyotsna - the assignDetectionsToTracks seems to have been added in R2012b (see the Computer Vision System Toolbox Release Notes). Which version are you using?

[Dima Lisin]

assignDetectionsToTracks is available in the Computer Vision System Toolbox, in the R2012b release or later.
