1. An image determination apparatus comprising: a first extraction unit that extracts a first set from an image including linear components that are line-shaped components, the first set including a linear component extending along a first direction and a linear component extending along a second direction intersecting the first direction; a second extraction unit that extracts a second set including a linear component extending along a direction different from the first direction and the second direction; a calculation unit that calculates a likelihood for the first set extracted by the first extraction unit in accordance with a relationship between linear components included in the first set, the likelihood being a likelihood of a table being formed; and a correction unit that corrects the likelihood calculated by the calculation unit in accordance with a relationship between the first set and the second set.
