● Image analysis uses pattern matching and Image analysis uses pattern matching and true-colortrue-color processing processing

● Calibration and supervised learning ensure Calibration and supervised learning ensure robust performancerobust performance

● Matching occurs in Matching occurs in a 3D color space a 3D color space (RGB, HSI, or LAB)(RGB, HSI, or LAB)

● Inspect Inspect complex complex and irregularand irregular color color patternspatterns

● Results are Results are independent of independent of sample orientation, sample orientation, spatial patterns, spatial patterns, and image and image complexitycomplexity
