Abstract: 
In this paper we present the problem that arise when template matching is applied to two images of the same objects displaced in both axis, and how this problem has effect at the detection of imperfections with precision near the pixel.
Also we show up a solution through the use of two master images. These images achieved through non-linear processing applied to original image based on morphological processing. In this way, we demonstrate that is possible to detect imperfections with resolutions near to pixel-level.
