WebMay 3, 2024 · LBPs are extracted, weighted, and concatenated in the same manner as the training data k-NN (with k=1) is performed with the distance to find the closest face in the training data. The name of the person associated with the face with the smallest distance is chosen as the final classification LBP looks at points surrounding a central point and tests whether the surrounding points are greater than or less than the central point (i.e. gives a binary result). Before trying out LBP on an image, it helps to look at a schematic of LBPs. The below code is just used to plot the schematic.
