Overcoming Poor Contrast Lighting with Smarter Vision Algorithms
Posted by Jeff Schmitz on Thu, Sep 09, 2010 @ 05:16 PM
Sometimes, light-engineered contrast seems too minimal for an application to succeed. Always, contrast—even with optimal lighting---is imperfect an inconsistent. This is where smarter image pre-processing tools come into play.
PPT VISION’s IMPACT machine vision software delivers over 25 distinct tools for extrapolating better contrast. Sophisticated Image Filtering algorithms such as edge enhancement, gaussian, median, average and binary filtering, light leveling, morphing and erosion controls maximizes contrast for marginal contrast images.
IMPACT’s Image Geometry tools use image sampling, line-profiling and other algoriths to further interpolate data from images with less-than-ideal contrast.
Lighting is the first tool for building a stable contrast foundation for vision systems. Image filtering and geometry are the next steps for robust contrast and reliable vision sensing.
