Model-Based PCB Inspection Technique Using Wavelet Transform

چکیده
Image difference operation is frequently used in automated printed circuit board (PCB) inspection system as well as in many other image processing applications. The inspection system performance depends critically on the speed of this operation, which is a common problem related to the image difference. The goal of our technique is to enhance the performance of the image difference operation in term of computation time using wavelet transform. The results of applying the technique to PCB images showed significant improvement on the traditional image differencing.
