1. An information processing apparatus comprising:
at least one memory that stores a program; and
at least one processor that executes the program to:
acquire a handwriting image;
generate a correct label image by binarizing the acquired handwriting image, the correct label image being indicative of handwriting pixels in the acquired handwriting image;
obtain a first scan image generated by reading a blank sheet;
acquire a noise image by cutting a part of the obtained first scan image out, a position of the part being randomly determined from the obtained first scan image;
synthesize the acquired handwriting image and the acquired noise image to generate a synthesized image; and
use the synthesized image and the correct label image as learning data for generating a learning model that is usable for estimating handwriting pixels from an image.
