A randomized CIE-lab evaluation of external bleaching therapy effects on fluorotic enamel stains
Objective: To evaluate the effect of external bleaching on the color and luminosity of fluorotic stains and adjacent, normally mineralized enamel areas by means of CIE-(*L,*a,*b) colorimetry. Materials and Methods: Eighteen adolescents with mild to moderate fluorotic stains were randomly allocated and randomly assigned by lot to either a bleaching ...

The Image Recognition of Mobile Robot Based on CIE Lab Space [PDF]
The image recognition of mobile robot is to extract the effective target information. The essence of image extraction is image segmentation. By extracting and distinguishing planar objects and three-dimensional objects, we propose two new algorithms. The color image is extracted by using CIE Lab Space.
