8-8 2次元フーリエ変換に基づくプリント基板の欠陥検出(第8部門 メディア工学3)

抄録

In the defect inspection of the part by using image processing, gaps are included between compared images. Recent digital cameras have much higher resolution, which makes the position gaps in inspected images greater. Even the situation including rotation and shift, this algorithm based on Fourier transform enables fast correction and defect detection.
