Definitions

  • the relative size of the object portion to the background portion, orientation, aspect ratio, resolution, lighting conditions, and/or other parameters of the original image may be determined, and the selection of one of the retrieved images of the same geographic location may be based on a degree of matching between the parameters of the original image and the retrieved images.
  • the parameters may be ranked, and an image having a higher degree of matching to some parameters may be selected over an image with a higher degree of matching of other parameters.
  • relative size and lighting conditions may be ranked higher than orientation and aspect ratio, and thus an image with similar lighting conditions and in which the relative size of the background is similar to the original image will be selected over an image in which those parameters don’t match but the other parameters do match.
  • the control circuitry 304 generates for display a new image comprising the subject portion 108 of the image 104 placed over the second image selected at block 420.
  • the control circuitry 304 may overlay the subject portion 108 of the image 104 onto the second image to generate the new image.
  • the control circuitry 304 identifies an object, point of interest, or landmark associated with the geographic location of the image 104 and determines whether that object, point of interest, or landmark is depicted in the second image.
  • control circuitry 304 may adjust the size of the subject portion 108 such that the relative size of the subject portion 108 to the size of the object in the second image remains the same as the relative size of the subject portion 108 to the size of the object in the image 104, as determined at block 808.

  • control circuitry is configured to retrieve the plurality of other images captured at the geographic location by:

Abstract

L'invention concerne des systèmes et des procédés de remplacement d'une partie d'arrière-plan d'une image. Un procédé illustratif comprend la réception d'une première image, l'identification d'une partie d'arrière-plan de la première image et d'une partie de sujet de la première image, la récupération de métadonnées associées à la première image, la détermination, en fonction des métadonnées, d'un emplacement géographique où la première image a été capturée, l'identification d'un monument associé à l'emplacement géographique, la récupération d'une seconde image représentant le monument, et la génération de l'affichage d'une troisième image comprenant la partie de sujet de la première image placée sur la seconde image.
