| 发明名称 | Pattern identifying apparatus, pattern identifying method and program | ||
| 摘要 | A pattern identifying apparatus comprises: a generating unit to generate, from input data corresponding to an area, accumulated information corresponding to each position in the area; plural storing units to hold the accumulated information for each dimension; a writing unit to write the accumulated information corresponding to each position to one of the plural storing units according to a predetermined rule concerning the corresponding position; a parallel reading unit to read the accumulated information in parallel from the plural storing units; a feature quantity calculating unit to calculate a feature quantity of a local area by using the read accumulated information; and an identifying unit to identify a predetermined pattern by using the plural feature quantities. The number of the storing units allocated to at least one dimension of the area corresponding to the input data and a reading interval of the accumulated information are in a coprime relation. | ||

| 主权项 | 1. A pattern identifying apparatus comprising: a generating unit configured to generate, from input data corresponding to an area, accumulated information corresponding to each position in the area; a plurality of storing units configured to hold the accumulated information; a writing unit configured to write the accumulated information corresponding to each position to one of the plurality of storing units according to a predetermined rule concerning the corresponding position; a parallel reading unit configured to read the accumulated information in parallel from the plurality of storing units; a feature quantity calculating unit configured to calculate a feature quantity of a local area by using the read accumulated information; and an identifying unit configured to identify a predetermined pattern by using the plurality of feature quantities, wherein the number of the storing units allocated to at least one dimension of the area corresponding to the input data and a reading interval of the accumulated information are in a coprime relation. | ||
