Figure 1From: Binary Biometric Representation through Pairwise Adaptive Phase QuantizationThe bit extraction framework based on the one-dimensional quantization and coding, where D denotes the number of features; b i denotes the number of quantization bits for the ith feature (i = 1,…, D), and S i denotes the output bits. The final binary string is S=S 1 S 2 ...S D .Back to article page
