A New Based Image Subtraction Algorithm for Bare PCB Defect Detection

Abstract

Various concentrated work has been developed in the area of computer vision applied to detection of failures on printed circuit boards (PCB’s), aiming at reducing the possibility of the occurrence of the fabrication defects. In this research, based on PCI’s – without mounting reference and test layout models, the objective is to study is the application of an image subtraction technique to the failure detection of those bare printed circuit boards layouts using image subtraction techniques during the image processing. By developing the primary subtraction algorithm, one may compare the efficacy of this image processing technique using linear simulations developed in MATLAB.
