Embodiment

[0035] Such as figure 1 As shown, the method for realizing fast fusion of face images in this example includes the following implementation steps:

[0036] 1. Perform face detection on the given target image and background image respectively, and obtain the corresponding target image facial feature points and background image facial feature points;

[0037] In this step, face detection is performed on the given target image and the background image using deep learning methods to obtain the corresponding facial feature points of the target image and the facial feature points of the background image.

[0038] 2. Normalize the facial feature points of the target image and the facial feature points of the background image;

[0039] In this step, the coordinates of the facial feature points of the target image and the facial feature points of the background image are expressed by normalization, and the center of gravity of the feature points is taken as the origin of the coordinat...

Abstract

The invention relates to the technical field of image processing, which discloses a method for realizing rapid fusion of human face images, and solves the problems of complicated operation and low processing efficiency of professional image processing software in the traditional technology. In the present invention, at first carry out human face detection respectively to given target image and background image and obtain corresponding human face characteristic coordinate; Then, carry out normalized representation to two groups of human face characteristic coordinates obtained; Estimate the face orientation of the background image, and then perform homography transformation on the target image; then, based on the facial feature points in the background image, deform and stretch the facial feature points in the target image; finally, transform The final target image and background image are automatically segmented, and an exponential attenuation gradient coefficient template with the distance between the pixel point and the feature boundary as a factor is applied to the image segmentation, so as to finally obtain the background image fused with the face image of the target image.

Description

technical field [0001] The invention relates to a method for realizing rapid fusion of human face images by using deep learning and digital image processing technology, and belongs to the technical field of image processing. Background technique [0002] With the rapid development of the entertainment industry such as film and television, and the increasing popularity of computer and image processing technology, young people, especially teenagers, are increasingly obsessed with stars in animation, movies, and TV dramas, especially the popularity of various time-travel dramas. , there have been many professional image processing software such as Photoshop and Meitu Xiuxiu to PS the images in the play, so as to obtain the renderings that they are also the characters in the play. In addition, in many "photographers" and "SLR fans" and various photo studios, there is also a large demand for "fast PS production" to meet the photo effects under various background images.
