Patch Classifier of Face Shape Outline Using Gray-Value Variance with Bilinear Interpolation

Figure 6

ROC curve according to the wide range of variance in the Multi-PIE. Red line is the ROC curve that is measured only by the threshold of the gray-value variance to the Multi-PIE. Blue line is the adjusted ROC curve considering the threshold of the gray-value variance to the Multi-PIE and features of the curve of the facial shape.
