# TrafficLightDetection

Set whether the yellow light detection should be enabled or not. However, for performance reasons, it is recommended to leave it disabled.

Set whether the performance mode should be enabled or not. This will increase the performance of the plugin by disabling the green light detection.

Enable this if you want to use the settings you set in the advanced settings tab.

The app will open another window where you can set your own screencapture area using the buttons to set the conrners.

You can set your screencapture area with these four sliders, X1 and Y1 set the top left corner and X2 and Y2 the bottom right corner of the screencapture area.
It does the same as the simple setup.

These window can output the results of the detection in different formats.

If enabled, the Window Width and Window Height sliders will no longer have any effect and the output window keeps the aspect ratio of the captured frame, however you can still set the size of the output window with the Window Scale slider.

You can set the size of the output window with these three sliders.

If enabled, the app tracks the detected traffic lights and confirms them with the YOLO object detection.
What this means: higher accuracy, but a small lag every time the detection detects a new traffic light.

If enabled, the unconfirmed or wrongly detected traffic lights will be shown in gray.

YOLO object detection has some pretrained models, which can be selected here. It is recommended to use the YOLOv5n model as it is the fastest model. Keep in mind that models with higher accuracy are slower and could lag the app more.
Don't forget to press "Save and Load Model" if you changed the model.

You can set your own 8-bit color masks in the RGB format for the detection here. The input field only accepts values from 0 to 255.

The size of the light of the traffic light must be within the allowed size you can set with the two sliders at the bottom.

The ratio of the width to the height of the light of the traffic light must be near 1 for a contour to be considered a traffic light.

The non-zero percentage of the light in a square around the traffic light must be near 78.5 for a contour to be considered a traffic light.

A contour will only be considered a traffic light if the other two lights of the traffic light are off.

You can set the min and max size of a contour to be considered as a traffic light.
