Why image pre-processing tools
Samantha Frost, 12-04-2012
Image pre-processing tools alter the raw image to emphasize desired features while minimizing undesirable features. This prepares the image for optimal performance by more powerful vision tools and can significantly improve the accuracy and robustness of the overall system. Pre-processing tools can:
- Increase the contrast between the part and its background,
- Mask insignificant and potentially confusing image features,
- Eliminate “hot spots” reflecting off the part surface, and
- Smooth rough surface textures.
Make sure that a complete set of image pre-processing tools is included with the vision system you choose.
