The raise in computing energy, for one, has helped machine vision solutions to gain in reputation in several automated inspection and measurement applications. In certain problems, the energy of optical systems has already been nicely recognised, but anything about machine vision is the fact that the feasible uses are only restricted by our imagination. Adventurousness, nevertheless, can be - pretty naturally - contained by the expenses as modern day optical systems could snowball into considerable costs with each of the specialised gear, software, configuration and assistance, which eventually slows down the progress of revolutionary solutions.
