Object enumerating apparatus and object enumerating method

An object enumerating apparatus characterized by comprising:

• binarized differential data generating means for generating and binarizing inter-frame differential data from moving image data comprised of a plurality of image frame data representative of a photographed object under detection;
• feature data extracting means for extracting feature data from three-dimensional data comprised of a plurality of the inter-frame binary differential data directly adjacent to each other through cubic higher-order local auto-correlation;
• learning means for generating a coefficient matrix for calculating the quantity of the object under detection based on feature data derived from a plurality of learning data which differ in at least one of a scale, a moving speed, and a moving direction of the object on a screen;
• quantity calculating means for calculating a quantity from a coefficient matrix previously generated by said learning means and the feature data derived from recognition data;
• and
• round-off means for rounding off an output value of said quantity calculating means to the decimal point to the closest integer.
