Abstract: There is provided with an information processing apparatus. An acquisition unit acquires a plurality of pattern discrimination results each indicating a location of a pattern that is present in an image. A selection unit selects a predetermined number of pattern discrimination results from the plurality of pattern discrimination results. A determination unit determines whether or not the selected predetermined number of pattern discrimination results are to be merged, based on a similarity of the locations indicated by the predetermined number of pattern discrimination results. A merging unit merges the predetermined number of pattern discrimination results for which it was determined by the determination unit that merging is to be performed. A control unit controls the selection unit, the determination unit, and the merging unit to repeatedly perform respective processes.

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.
