Image processing concept

  • The system measures the color in an N x M matrix

  • The matrix can be fixed or referring to an edge of the item

  • Based on the number of accepted colors a coverage and area are calculated

  • The system can count objects and classify them by shape and color

Teaching Colors

  • The system is trained after installation using reference images (colors)

  • It is possible to define a multitude of colors classes

  • Each color may have an infinite number of reference images

  • Multiple references are used to describe color variation within one color

  • The variation can be due to physical variations or real color changes
