Claim:
1. A part estimation apparatus comprising: one or more processors configured to: set, for each pixel in an image, a pixel of interest and a pair of pixels located at an equal distance from the pixel of interest on a straight line including the pixel of interest and perpendicular to a predetermined gradient direction, calculates an edge pair likelihood and generates an edge pair likelihood map indicating the edge pair likelihood for each pixel, the distance being determined based on the thickness of an estimation target part, the edge pair likelihood indicating a likelihood that each of the pair of pixels is an edge of the estimation target part; generate a continuity likelihood map indicating candidate regions respectively indicating the estimation target part based on the edge pair likelihoods of pixels included in a region assumed to represent the estimation target part extending in the gradient direction; and generate an integrated likelihood map indicating the candidate regions indicated in the continuity likelihood map by narrowing down the candidate regions based on a predefined condition.
