Stable inspection with higher
accuracy achieved through statistically
correct non-defective product images


For industrial products, using the same environment and same materials every time does not guarantee that the same products can be produced. Slight variances may occur from lot to lot.
DefFinder® creates statistically correct templates by training multiple non-defective product images.
Appearance defects such as scratches, dirt, and foreign materials can be consistently detected and inspected.
Inspections with variance are supported.

DefFinder® is a registered trademark of ViSCO Technologies Corporation. It is a visual inspection software that boasts over ten years of continued use in the field.

Use statistically correct non-defective products to enable consistently accurate inspections

When manufacturing conditions change, even if products are non-defective, there are slight variations in surface color, cutting plane, and molded surface. An inspection algorithm that presupposes these variations is necessary.

DefFinder® takes into account variances in non-defective products when performing inspections


ViSCO's inspection

Statistically correct non-defective
product images are used for inspection.


The effect of variances in shape and shading
of non-defective products is reduced.


Consistently accurate inspection is possible.

Ordinary Inspection

In order to handle variances due to differences in size or brightness,
the strictness of the threshold value is reduced.


Products that originally would have been determined defective are determined nondefective.


Defective products are released to the market.
