The confidence index, CI, measures the uniqueness of an orientation solution relative to the total number of possible votes.

CI is calculated using automated indexing of diffraction patterns from a ranking system, developed using the mechanism CI = (V 1-V 2)/V ideal where V 1 and V 2 are the number of votes for the first and second solutions and V ideal is the In the EBSD data sets that I am analyzing, I purposefully indexed only one of the phases. I still remove the low confidence index pixels from ebsd. But, surprisingly, I find different total number of grains for the following three methods: [12] and image quality mapping [13] to show the effect of the decreasing accelerating voltages on the detected thickness of grain boundaries. The confidence index is calculated by ranking of possible orientations (indexing solutions of the EBSD patterns) using a voting scheme for a given diffraction pattern. The Conference Board Consumer Confidence Index ® improved slightly in February, following an increase in January. The Index now stands at 130.7 (1985=100), up from 130.4 in January. The Present Situation Index – based on consumers’ assessment of current business and labor market conditions – decreased from 173.9 to 165.1. The confidence index is calculated by ranking of possible orientations (indexing solutions of the EBSD patterns) using a voting scheme for a given diffraction pattern. The formula for the confidence index is given as I c = ( V 1 − V 2 ) / V t o t a l where V 1 and V 2 are the number of votes for the first and second solutions and V total is Barron's Confidence Index: A confidence indicator calculated by dividing the average yield on high-grade bonds by the average yield on intermediate-grade bonds. The discrepancy between the yields

Confidence Index based metrics are confirmed to generally provide accurate estimates of the indexing success rate albeit increasingly conservative with decreasing indexing success. Abstract Electron Backscatter Diffraction (EBSD) provides a useful means for characterizing microstructure.

Symmetry is the revolutionary all-in-one EBSD (Electron Backscatter Diffraction) detector based on groundbreaking CMOS technology. Exceptional performance   Electron backscatter diffraction (EBSD) is a scanning electron microscope–based microstructural-crystallographic characterization technique commonly used in the study of crystalline or polycrystalline materials. Confidence Index based metrics are confirmed to generally provide accurate estimates of the indexing success rate albeit increasingly conservative with decreasing indexing success.
