This element consumes the detection metadata introduced in the buffer by our family of detection elements(TinyYoloV2). This element uses GstDetectionMeta. This element draws each bounding box with its respective label, using OpenCV.

Properties

The detectionoverlay element expose the following properties to control the boxes' thickness, color, etc. These properties are documented on the following table:

Property	Value	Description
font-scale	Double [0,100]	Scale of the font used on the overlay. 0 turns off the overlay
thickness	Double [1,100]	Thickness in pixels used for the lines
style	enum (0): classic (1): dotted (2): dashed	Line style of rectangle

Example
