Illuminate, Don't Manipulate Many nascent vision-system developers get bogged down trying to use software filter functions to smooth and enhance an image. Real machine-vision applications use filtering or smoothing functions infrequently because they take so much processing time. These functions process an entire image, so they can cause a production bottleneck by extending inspection times. Seasoned developers know that by properly illuminating the objects they want to inspect, they can obtain images with good contrast that highlight defects and reduce most noise arising from background reflections.
Many vendors supply lighting equipment specifically designed for machine-vision applications.
