plot

Plot re-identification (ReID) metrics

Since R2024a

Syntax

plot(metrics,type)

plot(metrics,type,Name=Value)

Description

plot(metrics,type) plots the ReID metrics metrics.

plot(metrics,type,Name=Value) specifies options using one or more name-value arguments. For example, LineColor="r" plots the specified metric type with a red line.

Input Arguments

metrics — ReID metrics

reidentificationMetrics object

ReID metrics, specified as a reidentificationMetrics object.

type — Type of metric to plot

"cmc" | "cmc-per-object" | "precision-recall"

Type of metric to plot, specified as one of these options:

• "cmc" — Cumulative matching characteristic (CMC) curve over the entire data set

• "cmc-per-object" — Cumulative matching characteristic (CMC) curve per object class

• "precision-recall" — Precision-recall curve

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: plot(metrics,"precision-recall",LineColor="r") plots the precision-recall curve with a red line.

ShowLegend — Option to display legend

true or 1 | false or 0

Option to display legend, specified as a numeric or logical 1 (true) or 0 (false). If you specify the plot type as "cmc-per-object" and there are 10 or fewer object classes, ShowLegend is true by default and the plot object function displays the legend.

Parent — Figure axes

gca (default) | Axes object

Figure axes, specified as an Axes object.

LineColor — Plot line color

[0 0 0] (default) | short or long color name | RGB triplet | three-column matrix of RGB triplets

Plot line color, specified as one or more 1-by-3 RGB triplets, or a long or short color name. If you specify the plot type as "cmc-per-object", you can specify a different color for each line by using a matrix in which each row is an RGB triplet. To specify one color for all lines, specify LineColor as a color name or a single RGB triplet.

LineWidth — Plot line width

2 (default) | positive integer

Plot line width, in pixels, specified as a positive integer.
