Abstract
An information processing apparatus includes at least one memory storing instructions, and at least one processor, which executes the instructions to extract a feature quantity from image data, obtain a partial feature quantity by extracting a particular position from the feature quantity, perform a predetermined arithmetic process by using the partial feature quantity, and restore a result of the predetermined arithmetic process to a size of the feature quantity.
Claims10
An information processing apparatus comprising:
- at least one memory that is configured to store instructions;
- and
- at least one processor that is configured to execute the instructions to;
- extract a plurality of feature quantity maps from image data;
- obtain a plurality of partial feature quantity which is smaller in size than the plurality of feature quantity maps by:
- dividing each of the plurality of feature quantity maps into a grid, and
- extracting one or more cells in a particular position in the grid from each of the plurality of feature quantity maps as the plurality of partial feature quantity;
- perform a predetermined process for calculating a matrix product of the plurality of partial feature quantity obtained from each of the plurality of feature quantity maps;
- and
- restore the matrix product calculated by the predetermined process to a size of the plurality of feature quantity maps.
