- Abstract:
- Abstract: A cylindrical projection method based on facial features is used to approximate the human head as a cylinder, which effectively solves the problem of visual inconsistency caused by different facial angles during image acquisition. SIFT feature matching algorithm is used to extract the feature vectors of two images, and the optimized RANSAC matching algorithm is used to eliminate false matches, thereby realizing image registration. Then fade-in and fade-out fusion algorithm is applied to smooth image transitions and eliminate stitching gaps. The experimental results show that the proposed algorithm can generate the panoramic image of face quickly and effectively, which lays a foundation for the follow-up face diagnosis in traditional Chinese medicine.
