Claim 11:
12. A system for detecting a target object on a document page, comprising:
one or more processors; and
at least one non-transitory computer readable medium storing instructions which, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
detecting a sample target area on a sample document page by detecting (i) a line within a predetermined distance from at least one of a first terminal side or a second terminal side of the sample document page and (ii) one or more textual characters positioned adjacent to the line, wherein the predetermined distance corresponds to a ratio of a total surface area of the sample document page;
generating an image by overlapping a plurality of sample document pages with one another;
detecting one or more cells within the sample target area on the image, wherein the sample target area includes a sample target object;
extracting one or more informational features from each of the one or more cells, wherein the one or more informational features define characteristics of a corresponding cell of the one or more cells;
training a machine learning model, using the one or more informational features extracted from each of the one or more cells, to detect the sample target object; and
detecting the target object on the document page using the trained machine learning model.
