Context-Sensitive Filtering in RLE for PCB Inspection

  title={Context-Sensitive Filtering in RLE for PCB Inspection},
  author={Fikret Erçal and Filiz Bunyak and Hao Feng},
This paper presents a fast printed circuit board (PCB) inspection methodology based on the segmentation of the PCB image into basic patterns and context sensitive filtering of the difference image for functional defect detection. The system consists of three parts: (i) segmentation of the artwork and test board images into basic patterns using the CAD data for the artwork, (ii) comparison of the test board image windows with the corresponding artwork image windows, (iii) context-sensitive… CONTINUE READING
