Color+ is a CVImager® module for color recognition. The color analysis is based on the HSI colors coding. The space diagram separates colors in 3 HSI components. The central axis is occupied by the white, the grey and black which have a saturation close to 0.
The use of HSI coding allows an accurate separation of colors and nuances. The system is nonsensitive to light intensity changes. Light intensity is still evaluated in the L component whereas the other components of system HSI remain practically unchanged.
