convertBufferedImage

public static java.awt.image.BufferedImage convertBufferedImage(java.awt.image.BufferedImage src,
                                                                int type)

Returns:

emulateCameraCapture

public static Mat emulateCameraCapture(Camera camera,
                                       java.io.File file)

Emulate an image captured by the given camera, but read it from a file. The image is adapted to the camera resolution, aspect ratio and to Units per Pixel if a upp.txt manifest is present side-by-side with the image file. This allows for pixel to lengths conversions typically performed by pipeline stages and pipeline callers to be accurate. The returned image is extend/cropped as needed.

Parameters:

camera -

file -
