Abstract
(EN)
The present application relates to an image segmentation method and apparatus, a computer device, and a storage medium. The method comprises: sequentially selecting a current image frame in a video according to a timing sequence; determining a reference image frame from image frames of which the timing sequences in the video are located in front of the current image frame; obtaining first position information of a target object key point in the reference image frame; carrying out affine transformation on the current image frame by referring to an affine transformation relation between the first position information and a target object key point template to obtain a target object diagram of the current image frame; performing key point detection on the target object diagram to obtain second position information of the target object key point; segmenting a target object from the target object diagram to obtain segmentation information of the target object; and segmenting the target object from the current image frame according to the segmentation information and the second position information. According to the solution of the present application, the calculated amount is reduced.

La présente invention concerne un procédé et un appareil de segmentation d'image, un dispositif informatique, et un support de stockage. Le procédé comporte les étapes consistant à: sélectionner séquentiellement une trame d'image courante dans une vidéo selon une séquence de minutage; déterminer une trame d'image de référence à partir de trames d'image dont les séquences de minutage dans la vidéo sont situées en avant de la trame d'image courante; obtenir des premières informations de position d'un point-clé d'objet cible dans la trame d'image de référence; réaliser une transformation affine sur la trame d'image courante en se référant à une relation de transformation affine entre les premières informations de position et un gabarit de point-clé d'objet cible pour obtenir un diagramme d'objet cible de la trame d'image courante; effectuer une détection de points-clés sur le diagramme d'objet cible pour obtenir des secondes informations de position du point-clé d'objet cible; segmenter un objet cible à partir du diagramme d'objet cible pour obtenir des informations de segmentation de l'objet cible; et segmenter l'objet cible à partir de la trame d'image courante selon les informations de segmentation et les secondes informations de position. Selon la solution de la présente invention, la quantité calculée est réduite.
