Binary custom properties support allows for the attaching of arbitrary binary values; for example, an audio recording or scanned image, to a human task on the fly, using key-value pair semantics.

This new algorithm USES the background subtraction method to get the foreground image, and then gets the binary image using threshold value and makes the morphology processing.

The materials such as wood, cast and steel products, because their density are more homogeneous, so their image profiles which are inspected by ICT device must be binary-value images approximately.
