Human hairstyle generation method based on multi-feature retrieval and deformation

Abstract

A human hairstyle generation method based on multi-feature retrieval and deformation includes: acquiring a hair style mask; identifying feature points of a human face and match the feature points with a hair style database; aligning an image with a standard human face to acquire a corresponding hair region; calculating Minkowski distances between the hair region and hair masks of all frontal faces in the hair style database; assigning corresponding weights after sorting the Minkowski distances from small to large; training a deep learning network to detect hair styles of hair basic blocks at different scales; and taking out a most similar hair style picture. The present invention utilizes a single frontal photo of the human face, and retrieves a three-dimensional hair model most similar to the photo by retrieving a database in a mass three-dimensional hair style database, to avoid manual modeling, thereby improving efficiency and ensures high fidelity.
