Abstract

PURPOSE: A method and a system for automatically synthesizing a hair style are provided to automatically extract a face area from image data and automatically synthesize the face area with a hair style wanted by a user by using face recognition technique. CONSTITUTION: A photographing and input unit(110) photographs a person at a specific place for inputting an image signal to a synthesis reference point extracting unit(120). The synthesis reference point extracting unit extracts a face area by separating the face area from a background area, and extracts configuration components from the extracted face area for setting synthesis reference points on the face image. A hair style synthesizing unit(130) matches the extracted synthesis reference points with synthesis reference points set on a hair style to synthesize a hair style image with the face image.

Description

Automatic hairstyle simulation method and system}

The present invention relates to a system and method for automatically synthesizing a hairstyle to a photographed human image, and in particular, removes a background area based on a color of a face, and sets a face component on a extracted face to have characteristics of the position and size of a minimum proximity rectangle. The present invention relates to an automated and fast hairstyle synthesis method by setting a reference point to be combined with a hairstyle by extracting the information and matching the reference point set to the hairstyle.

Hair style synthesis has been tried in many fields, but prior to the development of the conventional face image recognition technology, most users acquire a photographic image by matching their face, and then manually synthesize the hairstyle by adjusting the position on the screen. This is a conventional technique.

This conventional manual hairstyle synthesis method has a lot of problems in the environment that is actually utilized in the processing time and user convenience.

In order to solve the problems of the prior art as described above, in the present invention, by using the image processing technology to automatically extract the facial region, facial components from the input image to set the hairstyling synthesis reference point, automatic hairstyling synthesis The object of the present invention is to provide a method and system for implementing the system.

The configuration of the present invention for solving the above problems, by taking a face image signal at a predetermined location, extracts the face region by separating the face region and the background region, eyes, eyebrows, mouth required for synthesis in the extracted face region The method may extract the position and size information of the face edge, set a synthesis reference point, and synthesize it according to the synthesis reference point of the selected hairstyle.

Referring to the accompanying drawings, the operation of the present invention according to each configuration described above are as follows.

1 is a block diagram showing an automatic hairstyle synthesizing system according to the present invention, Figure 2 is a flow chart showing a hairstyle automatic synthesis method according to the present invention.

First, referring to FIG. 1, a configuration of the system includes a photographing and input unit 110, a synthesis reference point extracting unit 120, and a hair style synthesizing unit 130.

The photographing and input means 110 photographs a person at a specific place and inputs it to the synthesis point extracting means 120 as an image signal.

The synthesis reference point extracting unit 120 extracts the face region by separating the face region from the background region in the input image, and extracts components such as eyes, eyebrows, mouth, chin, and face edges from the extracted face region to extract the synthesized reference point. Set on the extracted face image.

The hairstyle synthesizing unit 130 synthesizes the hairstyle image on the extracted face image by matching the extracted synthesis reference point and the synthesis reference point set in the hairstyle.

Next, the method for automatically synthesizing the hairstyle will be described with reference to FIG. 2.

A method of automatically compositing a hair style by extracting a face image from an input human image and setting a synthesis reference point from the extracted face image to match the reference point set in the selected hairstyle,

(a) setting a synthesis reference point in anticipation of a position of a component of a face to be synthesized in the hairstyle image information (200); and

(b) taking an image of a person and inputting it as an image signal (210); and

(c) extracting a face region from the input image with face characteristic information (face color, face size, etc.) (220); and

(d) extracting the component (230) from the extracted face region with characteristic information (position, size, color, etc.) of the facial component; and

(e) setting a reference point for synthesizing the hairstyle with the location information of the component (240); and

(f) synthesizing the two images such that the hairstyle synthesis reference point on the extracted face image and the synthesis reference point on the hairstyle image are matched with each other (250).

As described above, according to the present invention, a face image is acquired by using face recognition technology, and a synthesis reference point is set based on the positional information of the components in the acquired face image and matched with the synthesis reference point preset in the hairstyle. Synthesis allows easy and convenient implementation of conventional passive and incorrect synthesis techniques.
