Digital image processing applied in determination of misplaced components on a PCB, marked with colour code

The paper presents an application for automatic determination of misplaced components or missing components mounted on a PCB. The determination is realized by image processing techniques using frame processing methods. The advantage of using this inspection method is that of automation facilities and quickly determination of misplaced components marked with colour code. The proposed algorithm can be implemented in different programs as Matlab, Imagproc, so on....
