Components Overview

All components available in Metavision Designer can be roughly grouped into categories based on their function.

Producers

Producers are components producing data, for example by reading it from a file. They are generally used to produce data that will be processed by other components.

Algorithm Name	Module
`metavision_designer_core.CdProducer`	Core
`metavision_designer_core.ExtTriggerProducer`	Core
`metavision_designer_core.FileProducer`	Core
`metavision_designer_core.FileProducerTrigger`	Core

Loggers

Loggers are components processing data in order to write logs or compute statistics.

Algorithm Name	Module
`metavision_designer_core.StreamLogger`	Core
`metavision_designer_cv.EventCounter`	CV

Processors

Processors are components that can be used to process data either to change some of their characteristics (e.g. flip the x coordinate of every event) or perform some advanced analysis (e.g. tracking objects or extracting spatio/temporal patterns).

`metavision_designer_cv.TrailFilter`	CV

Renderers

Renderers are components displaying data on the screen.

Algorithm Name	Module
`metavision_designer_3dview.Image3dDisplayOSG`	3dview
`metavision_designer_cv.ImageDisplayCV`	CV
