Abstract

The embodiment of the invention provides an image processing method and an image processing device. The method comprises the following steps: face parts of a source image and a target image are acquired; a comparative analysis is made on the face parts of the source image and the target image to obtain a fusion line between the face parts of the source image and the target image, wherein the fusion line is a pixel line with the minimum image difference in areas above the eyebrows of the face parts of the source image and the target image and is located in the areas above the eyebrows of the face parts; and the face parts of the source image and the target image are respectively segmented by taking the fusion line as a dividing line to correspondingly obtain a first part and a second part, and in the target image, the first part of the face part of the target image is replaced with the first part of the face part of the source image to obtain a processed image, wherein the first parts are parts including the noses in the face parts. The image processing method and the image processing device provided by the embodiment of the invention can be applied to image processing in which the face of a target image is replaced with the face of a source image, and the image processing effect after replacement can be improved.

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...
