Title
(EN) METHOD, DEVICE, AND ELECTRONIC APPARATUS FOR IMAGE ENHANCEMENT
(FR) PROCÉDÉ, DISPOSITIF ET APPAREIL ÉLECTRONIQUE POUR L'AMÉLIORATION D'IMAGES
(ZH) 用于实现图像增强的方法、装置和电子设备
Abstract
(EN)
A method, a device, and an electronic apparatus for image enhancement are provided. The method comprises: performing a filtering processing on an image to be processed to obtain a filtered image (S500); determining a similarity between pixels of the image to be processed and a target area of a target object in the image to be processed (S510); and fusing the image to be processed and the filtered image according to the similarity, such that the filtering effect is stronger for pixels having higher similarity with the target object in the image to be processed, and is weaker for pixels having lower similarity with the target object in the image to be processed (S520).
(FR)
La présente invention concerne un procédé, un dispositif et un appareil électronique permettant d'améliorer des images. Le procédé comprend : la réalisation d'un traitement de filtrage sur une image à traiter pour obtenir une image filtrée (S500); la détermination d'une similarité entre des pixels de l'image à traiter et une zone cible d'un objet cible dans l'image à traiter (S510); et la fusion de l'image à traiter et de l'image filtrée selon la similarité de sorte que l'effet de filtrage est plus fort pour des pixels présentant une plus grande similarité avec l'objet cible dans l'image à traiter et est plus faible pour des pixels présentant une moindre similarité avec l'objet cible dans l'image à traiter (S520).
(ZH)
一种用于实现图像增强的方法、装置和电子设备,其中的方法包括:对待处理图像进行滤波处理,获得滤波处理后的图像(S500);确定所述待处理图像中的像素点与所述待处理图像中的目标对象的目标区域的相似度(S510);将所述相似度、所述待处理图像和所述滤波处理后的图像进行融合,使得所述待处理图像中与所述目标对象的相似度越高的像素点的滤波效果越强,所述待处理图像中与所述目标对象的相似度越低的像素点的滤波效果越弱(S520)。
