Abstract:
According to one embodiment, a moving object contour extraction apparatus includes a contour acquisition unit and a contour correction unit. The contour acquisition unit is configured to acquire a contour of a moving object in each image slice. The contour correction unit is configured to correct the contours of the moving object in image slices of at least one image slice time series based on motion trend information of the moving object in each of a plurality of image slice time series.
