Claim Text:
1. An object detection apparatus comprising: at least one processor and at least one memory coupled to each other and cooperating to act as: a first detection unit configured to detect a first portion of an object from an input image; a second detection unit configured to detect a second portion different from the first portion of the object from the input image; a first estimation unit configured to estimate a third portion different from the first portion and the second portion of the object based on the first portion when the first detection unit detects the first portion; a second estimation unit configured to estimate a fourth portion different from the first portion and the second portion of the object based on the second portion when the second detection unit detects the second portion; a first score correction unit configured to correct the third portion with a correction coefficient based on the first detection unit; a second score correction unit configured to correct the fourth portion with a correction coefficient based on the second detection unit; a determination unit configured to determine whether the third portion and the fourth portion, which have been respectively estimated by the first and second estimation units, meet a predetermined condition; and an output unit configured to output, if the determination unit determines that the third portion and the fourth portion meet a predetermined condition, a detection result of the object based on at least one of a detection result of the first or second detection unit and an estimation result of the first or second estimation unit, wherein the determination unit calculates a degree of matching between the third portion and the fourth portion respectively estimated by the first and second estimation units based on a ratio of overlapping of the third portion and the fourth portion respectively estimated by the first and second estimation units, and determines, if the degree of matching is a predetermined threshold value or more, that the third portion and the fourth portion respectively estimated meet the predetermined condition, and wherein the first portion includes the third portion, and third portion includes the second portion, wherein the correction coefficient depends upon an estimation performance of the first estimation unit and the second estimation unit of a common area which corresponds to the third portion and the fourth portion.
