The function set to the output matrix either the value from the first input matrix if corresponding value of mask matrix is 255, or value from the second input matrix (if value of mask matrix set to 0).In order to map the 12 bit PixelFormats to 16 bit OpenCV Matrix Type, the Baumer GAPI buffer memory data need to be shifted by 4 bits (multiply with 16) using the OpenCV ConvertTo () command. Similarly, 10 bit PixelFormats such as Mono10 can be converted by shifting the data by 2 bits or multiplying with factor 64.In OpenCV 4.2, only one streaming source is allowed per pipeline – this requirement will be relaxed in the future. OpenCV comes with a great class cv::VideoCapture and by default G-API ships with a stream source class based on it – cv::gapi::wip::GCaptureSource. Detailed Description.
