Abstract

Embodiments of the present invention provide an image processing method and device. The method includes: obtaining the face parts of the source image and the target image; performing comparative analysis on the face parts of the source image and the target image, and obtaining a fusion line between the face parts of the source image and the target image, and the fusion line is the source image The pixel line with the smallest image difference in the area above the eyebrows of the face part of the target image, and the fusion line is located in the area above the eyebrows of the face part; the source image and the face part of the target image are separated by the fusion line as the dividing line to obtain corresponding to the first part and the second part, and in the target image, replace the first part of the face part of the source image with the first part of the face part of the target image to obtain the processed image; wherein, the first part is in the face part Including the nose part. The embodiment of the present invention can be applied to the image processing of the target image of human face replacement of the source image, and can improve the image processing effect after replacement.

Description

technical field [0001] Embodiments of the present invention relate to image processing technologies, and in particular, to an image processing method and device. Background technique [0002] Face image deformation processing is an important aspect of image processing, which is widely used in medical treatment, criminal detection, face image synthesis, 3D face image reconstruction, image retrieval, and face plastic surgery. Face replacement is a kind of face image deformation. [0003] When the existing method replaces two face images, the method of image fusion is usually adopted. The transition deformation method in movie special effects is: first, the source image and the target image are respectively deformed by relevant deformation algorithms, and then the two deformed images are fused together to obtain an intermediate image, which is the deformation process. deformed image. The common method of face replacement is to replace all the faces in the deformed source ima...
