Abstract
Object detecting apparatus and method enable to easily and accurately generate a feature quantity for detecting an object at low cost. To achieve this, in the object detecting apparatus and method, a value is assigned in consideration of relations of rotation and reversal in uniform patterns by using a small-sized conversion table, and, an ULBP feature quantity after rotation and reversal is generated from a previous ULBP feature quantity by simple calculation without using a conversion table indicating a correspondence relation between previous values and values after rotation and reversal.
