<P>PROBLEM TO BE SOLVED: To suitably divide a dynamic picture image into areas. <P>SOLUTION: An area division device includes: corresponding point estimation means 11 of estimating correspondence of each pixel between adjacent frames of the dynamic picture image; border candidate image generation means 12 of generating images of a plurality of resolutions from the original image, adding noise, connecting similar pixels, and putting the images together to generate a border candidate image; area division means 13 of finding a reliability function representing likelihood of a corresponding point using a cost function associated with the corresponding point, and performing area division according to reliability of a pixel calculated with the reliability function; corresponding point information correction means 15 of correcting the reliability function according to a difference between the border candidate image and an area division processing result; and repetitive condition regulation means 14 of determining whether area division is adequate based upon a degree of coincidence between last area division and current area division after the reliability function is corrected, and repeating processing by the corresponding point information correction means 15 and the area division means 13 when the area division is not adequate, or ending the area division processing when the area division is adequate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
