Abstract
A line-of-movement generating apparatus includes an acquisition unit, a detection unit, an extraction unit, a setting unit, a calculation unit, and a confirmation unit. The acquisition unit acquires images captured by an image capturing device at respective multiple time points. The detection unit detects one or more moving objects from the images. The extraction unit extracts a line of movement of each of the detected one or more moving objects. The setting unit sets a region where a line of movement tends to have a missing portion in an image captured by the image capturing device. The calculation unit calculates a likelihood indicating a degree of certainty of the extracted line of movement of each of the one or more moving objects. The confirmation unit confirms a line of movement of the one or more moving objects on the basis of the calculated likelihood.
