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).
