1. A recording medium determination apparatus comprising:
at least one processor; and
at least one memory in communication with the at least one processor and having stored thereon instructions which, when executed by the at least one processor, cause the recording medium determination apparatus to act as:
an image data acquisition unit configured to acquire image data obtained by capturing an image of a predetermined area in a recording medium;
a first extraction unit configured to extract a first feature amount by processing the image data using a first parameter;
a second extraction unit configured to extract a second feature amount by processing the image data using a second parameter different from the first parameter; and
a determination unit configured to determine a type of the recording medium based on the first feature amount and the second feature amount,
wherein a pixel having a maximum value is extracted from neighboring pixels from the predetermined area of the image captured in the recording medium to extract the first feature amount and the second feature amount,
wherein the determination unit includes a first determination unit and a second determination unit,
wherein the first determination unit determines, based on the first feature amount extracted by the first extraction unit, which group the recording medium belongs to among groups into which a plurality of types of recording media is classified based on a feature of image data,
wherein the second determination unit determines, based on the second feature amount extracted by the second extraction unit, which type the recording medium is among types of recording media belonging to the group determined by the first determination unit, and
wherein the first parameter is generated by performing learning in such a manner that the group determined by the first determination unit matches a group indicated by a correct answer label when image data is input to the first extraction unit using image data of a recording medium of a type belonging to each group as input data and a group corresponding to the input data as the correct answer label.
