processing_function()

template<GpuImageSource T>

void MayaFlux::Buffers::ImageCVProcessor< T >::processing_function ( const std::shared_ptr< Buffer > &  )

inlineoverridevirtual

Download the current GPU image, run the VisionSequence, store the result.

No-op if the buffer has expired or the image is unavailable.

Parameters

buffer

The GpuImageSource buffer to read from.

Implements MayaFlux::Buffers::BufferProcessor.
