Abstract: An object extraction method comprising the steps of comparing each portion of first image data obtained by capturing an extraction object with another portion of the first image data or second image data, thereby generating shape data as an image representing a provisional region of the extraction object in the first image data, and matching a contour of the shape data to a contour of the extraction object by using the first image data and the provisionally generated shape data.

Abstract: An image displaying apparatus includes an image storing unit storing image data containing two or more objects. An extracting unit extracts individual data from the object of the image data. An input unit inputs additional partial image data, and attribute data representing a corresponding relationship of at least part of the image data to the additional partial image data. An associating unit associates the additional partial image data with an individual data of the image data, using the attribute data input via the input unit. A synthesizing unit modifies a data content regarding at least part of the image data, which is associated by the associating unit, and synthesizes the modified content with the image data stored in the image storing unit.

Abstract: Rectangles R(i−1), R(i), and R(i+1) are set to surround three temporally continuous frames f(i−1), f(i), and f(i+1). Difference images fd(i−1, i) and fd(i, i+1) are obtained on the basis of the inter-frame differences between the current frame f(i) and the first reference frame f(i−1) and between the current frame f(i) and the second reference frame (i+1). Background regions are respectively determined for polygons Rd(i−1, i)=R(i−1) or R(i) and Rd(i, i+1)=R(i) or R(i+1), and the remaining regions are selected as object region candidates. By obtaining the intersection between these object region candidates, an object region O(i) on the current frame f(i) can be extracted.
