The image analysis use case provides the application with an accessible image to perform some kind of processing. The application implements an analysis method executed on each image. Images are processed by passing an executor in which image analysis is performed via a ImageAnalysis.Analyzer() . Only one analyzer can be registered at a time: registering a new analyzer replaces the existing one.

Image analysis can operate in two modes:

• in blocking mode, the executor receives images from the camera in sequential order. This means that, if the analysis method takes too long, images will accumulate in a processing buffer. Processed images may then no longer be current;

• in non-blocking mode (the mode we're using here), the executor receives the last available...
