The Blur filter blends the light edges outward, making them appear larger and allowing for them to be detected more accurately. The Real-time Shade Correction filter eliminates background interference and variations in illumination, which further increases stability. As a result, it is possible to accurately count the number of packages.
A vision system was already used for counting, but there was not sufficient contrast between packages and the background, leading to miscounts. The XG-7000 Series makes it possible to stably detect the edges of each packet by using the Real-time Shade Correction filter with a Blur filter.
