Abstract: A search server includes an extracting unit that extracts a search target matching a search condition based on profile data, and a transmitting unit that transmits the search target to a user terminal. The search condition includes a first frequency of appearance for each of one or more specified topics specified by a user in a first specified period and a second frequency of appearance for each of the specified topics in a second specified period being later than the first specified period. The extracting unit extracts the search target where the frequency of appearance for each of the specified topics in a first search target period and a second search target period being later than the first search target period are identical or similar to the first frequency of appearance and the second frequency of appearance, respectively.

Abstract: There are provided a foreground region extraction program, a foreground region extraction apparatus, and a foreground region extraction method capable of clipping an object region (foreground region) at high speed. An arrangement is as follows: Foreground pixels designated by a user and background pixels designated thereby are each set as a reference pixel to identify, from among a plurality of divided color spaces created by a three-dimensional color space being divided, the divided color space to which each of the reference pixels belongs, as a reference divided color space.

Abstract: There are provided an image processing apparatus, an image processing method and an image processing program for transforming a target image having no contour of straight line portions. An ellipse E1 by which the target image is approximated is calculated (S20), a center candidate OA of the target image is decided (S21), a first polygon P1 associated with the ellipse and the center candidate is calculated (S22), a projective transformation matrix for projectively transforming the first polygon into a second polygon P1? associated with an ellipse whose center is a point where the center candidate is projectively transformed is calculated (S23), and the target image is projectively transformed based on the projective transformation matrix to obtain a transformation image (S24).
