Embodiment Construction

[0059] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0060] The purpose of the present invention is to detect the position of the human face from an image, obtain the outline of the face, and finally provide the classification result. see Figure 4 , the implementation steps are divided into three steps, namely face location, face contour detection and face classification.

[0061] Step (1): face positioning,

[0062] Using the existing Harr detection method can effectively detect the position of one or more faces in any image, and give the coordinates of the vertices of the rectangular area of ​​the face. In the following description, we only take a face image as an example to explain. When there are more than one face in the original image, the method can detect the position and range of each face one by one.

[0063] Referring to Fig. 1, the coordinates of the four corners defining the detected face area are A, ...

Abstract

The invention relates to an image processing method, in particular to a detecting and classifying method of facial-form contours. The invention aims at solving the problems in the prior art that the accurate facial-form contour can not detected and the techniques can not be really applied to the facial-form classification. The invention provides the technical proposal that: the step 1, the human face is positioned; the step 2, the facial contour is detected: an egg-shaped face is set into a vector closed and symmetrical curve Lm that consists of one or a plurality of points, and then, the forehead height, the chin height, the abscissa position that keeps to the sides of the left cheek and the right cheek extremely and the gill shape are modified; the step 3, the facial forms are classified. The invention can provide the effective and automatic image processing measures for a plurality of industries such as image design, facial make-up, hairdressing, jewelry, face-painting, entertainment, and the like, and provides the automated and objective technical support for a plurality of applied industries.

Description

technical field [0001] The invention relates to an image processing method, in particular to a method for detecting and classifying face contours. Background technique [0002] With the improvement of people's material living standards in our country, people's demand for self-image design is growing rapidly. At the same time, the corresponding service industries, such as image design, hairdressing, clothing jewelry, makeup and entertainment, are also moving towards individuality. Development in the direction of internationalization, specialization, science and informatization. In many occasions in these fields, when providing products and services, service providers need to make corresponding designs or recommendations based on the customer's face shape, such as hairstyle selection, jewelry wearing, etc. In daily life, including from the historical records of our country, there are some typical classification methods for people’s faces. For example, one method divides faces...
