A class for creating a plot for displaying detection performance with the axes scaled and labelled so that a normal Gaussian distribution will plot as a straight line.
- The y axis represents the miss probability.
- The x axis represents the false alarm probability.

Create a figure to plot the DET-curve. Default plot everything on one single figure
Parameters: | idx – Index of the figure to create. Default is 0. |

Plots two lines indicating Doddington’s Rule of 30 points: one for false alarms and one for misses. See the documentation of plot_DR30_fa and plot_DR30_miss for details.
Parameters: |
|
---|
Plots a vertical line indicating the Doddington 30 point for false alarms. This is the point left of which the number of false alarms is below 30, so that the estimate of the false alarm rate is no longer good enough to satisfy Doddington’s Rule of 30.
Parameters: |
|
---|
Plots a horizontal line indicating the Doddington 30 point for misses. This is the point above which the number of misses is below 30, so that the estimate of the miss rate is no longer good enough to satisfy Doddington’s Rule of 30.
Parameters: |
|
---|
Places the mindcf point for the current system.
Parameters: |
|
---|
Plots a DET curve using the ROCCH.
Parameters: |
|
---|
Plots a DET curve.
Parameters: |
|
---|
Sets the scores to be plotted. This function must be called before plots are made for a system, but it can be called several times with different systems (with calls to plotting functions in between) so that curves for different systems appear on the same plot.
Parameters: |
|

Parameters: |

Modify the title of a DetPlot object
Parameters: | title – title of the plot to display |
