In previous newsletters, we have discussed the need to completely separate application software and hardware using so-called APIs (Application Programming Interfaces). For image processing purposes, under Windows, this API is called 'DirectX' / 'DirectShow'.

It allows the interactive measurement of basic geometrical features in image objects.
