Cognex AI image analysis software is as reliable as human inspectors for detecting surface appearance defects, but with the speed of a computerized system. The defect detection tool can create reliable shape and texture models based on training images, and can find defects on rough materials even with poor image quality under standard lighting. It then identifies surface texture changes as anomalies, and then uses the classification tool to classify them as collisions or scratches. Continuously providing high-quality products to the market can improve customer satisfaction and improve brand loyalty.
