Face image processing method and device

Abstract

A face image processing method disclosed by the present invention comprises the following steps of obtaining the face contour of a face image, and detecting whether a zooming instruction to the face image exists; when the zooming instruction is detected, carrying out the zooming processing on the face contour of the face image, wherein the shrinking proportion is larger at the area more closer to the center of the face contour during the zooming processing; obtaining the face image after the zooming processing. The present invention also discloses a face image processing device. According to the present invention, the face central protruded part in the close-range shot face image is shrunk, the area at the face edge is stretched, thereby correcting the deformation caused by amplifying the face central part in the face image effectively, and enabling the face in the close-range shot face image to be more natural and real.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a face image processing method and device. Background technique [0002] With the development of smart terminals, users are more and more accustomed to taking pictures with smart terminals. However, when a user uses a smart terminal to take a close-up shot such as a selfie, because the shooting distance is too close, and the camera is close to a point for imaging, the face in the selfie photo is often enlarged in the central part of the face, making the selfie photo The faces appear distorted and unreal. [0003] Such as figure 1 , figure 2 as shown, figure 1 Schematic diagram of face imaging when shooting at a long distance; figure 2 It is a schematic diagram of face imaging when shooting at close range. figure 1 In the long-distance shooting, the distance between the various parts of the face and the lens in the long-distance camera imaging is almost th...

Problems solved by technology

while in figure 2 In close-range shooting, for example, when the user uses the front camera of the terminal to take a selfie, because the distance between the lens and the face is very close, the distance between each part of the face and the lens varies greatly, and the closer the part to the center of the face and the lens The closer the distance is, the closer to the center of the face in the face image formed when shooting at close range will account for a larger proportion of the picture compared to the face in the face image formed when shooting at a long distance. The face image in the face image formed during shooting is deformed, unreal and natural
