Abstract:
(EN) Provided are an image processing method and apparatus, which fall within the technical field of image processing. The method comprises: acquiring a differential image of an original image; according to a pixel value of a pixel point in the differential image, acquiring an edge characteristic parameter of a first pixel point of an intermediate image; according to the edge characteristic parameter, obtaining an edge characteristic parameter of a second pixel point in a target image; and according to the edge characteristic parameter of the second pixel point, obtaining the target image. The present disclosure satisfies the requirement for scaling by any multiples.
(FR) L'invention concerne un procédé et un appareil de traitement d'images, qui relèvent du domaine technique du traitement d'images. Le procédé consiste à : acquérir une image différentielle d'une image d'origine ; selon une valeur de pixel d'un point de pixel dans l'image différentielle, acquérir un paramètre de caractéristique de bord d'un premier point de pixel d'une image intermédiaire ; en fonction du paramètre de caractéristique de bord, obtenir un paramètre de caractéristique de bord d'un second point de pixel dans une image cible ; et selon le paramètre de caractéristique de bord du second point de pixel, obtenir l'image cible. La présente invention satisfait l'exigence de mise à l'échelle par n'importe quel multiple.
(ZH) 本公开提供了一种图像处理方法及装置,属于图像处理技术领域。方法包括:获取原始图像的差异图像;根据差异图像中像素点的像素值,获取中间图像的第一像素点的边缘特性参数;根据边缘特性参数,得到目标图像中第二像素点的边缘特性参数;根据第二像素点的边缘特性参数,得到目标图像。本公开满足了任意倍缩放的需求。
