Classifying Dementia Using Local Binary Patterns from Different Regions in Magnetic Resonance Images

Figure 1

(a) Demonstrates LBP thresholding. A neighbour to a center pixel is set to one if it has equal or higher pixel value and zero if it has lower pixel value. In an anticlockwise manner, every neighbour is multiplied by powers of two and summed as demonstrated in (9). (b) demonstrates how the radius and number of samples can be varied in the choice of neighbourhood. (b) Left figure with small radius and 8 samples. Right figure with large radius and 16 samples.
