<p>We propose two methods and an apparatus for counting stacked plywood sheets. The first method is based on the normalized cross-correlation method. In this method, an inspection image is first scanned and the cross-correlation of the template image of the stacked plywood cross-section is then investigated in order to obtain the number of normalized cross-correlation maxima, which indicates the number of plywood sheets. The second method is based on the cross-validation method and uses an estimation model to determine the central portion of each plywood sheet in the cross-section of the plywood stack. An application example demonstrates that the methods proposed can reduce the time required for counting plywood sheets by more than 40% as compared to current methods.</p>
