This element consumes the classification metadata introduced in the buffer by our family of classification elements: InceptionV2 and InceptionV4. This element uses GstClassificationMeta. This element finds the highest probability among the meta and adds a text overlay to the buffer that displays this information.

Properties

The classificationoverlay element exposes the following properties to control the overlay size, position, 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
labels	String	Semicolon separated string containing inference labels. For example: labels="cat;dog;bird"

Example
