LBP (Local Binary Pattern) is a texture descriptor that compares each pixel with its neighboring pixels, records whether each neighbor is brighter or darker as a bit, and combines these into a single binary pattern value. Because it is simple to compute and relatively robust to lighting changes, it is widely used as a feature for face recognition, texture classification, and object detection cascades. For a whole image, a histogram of the pattern values is used as the feature vector.
