Abstract
(EN)
The present application relates to an image processing method and apparatus, an electronic device and a storage medium, belonging to the technical field of computers. The method comprises: when a preset fly-away special effect instruction is received, building a facial grid and a five-sense-organ grid in an image to be processed; determining a facial image in an image region covered by the facial grid; setting a pixel value of each pixel in the facial image as a target pixel value; in the image to be processed, extracting an image region covered by the five-sense-organ grid to obtain a five-sense-organ image; and mapping the five-sense-organ image onto the facial image according to a preset triangular mapping algorithm and a preset shift amount to obtain a processed target image. By using the present application, a fly-away special effect can be added to an image, thereby enhancing the user experience.

L'invention concerne un procédé et un appareil de traitement d'image, un dispositif électronique et un support d'informations, qui se rapportent au domaine technique des ordinateurs. Le procédé consiste : à construire, lorsqu'une instruction d'effet spécial de fuite prédéfinie est reçue, une grille faciale et une grille des organes des cinq sens dans une image à traiter ; à déterminer une image faciale dans une région d'image couverte par la grille faciale ; à régler une valeur de pixel de chaque pixel dans l'image faciale en tant que valeur de pixel cible ; dans l'image à traiter, à extraire une région d'image couverte par la grille des organes des cinq sens afin d'obtenir une image des organes des cinq sens ; et à mapper l'image des organes des cinq sens sur l'image faciale selon un algorithme de mappage triangulaire prédéfini et une quantité de décalage prédéfinie afin d'obtenir une image cible traitée. Au moyen de la présente invention, un effet spécial de fuite peut être ajouté à une image, ce qui permet d'améliorer l'expérience utilisateur.
