Problems solved by technology

The parametric skin color model assumes that the skin color distribution conforms to a certain type of specific mathematical function, and determines the corresponding parameters through the training data. The model is usually assumed to obey single Gaussian distribution, multi-Gaussian distribution, ellipse distribution, etc. It has generalization ability in sufficient cases, but the assumption of its distribution form lacks convincing proof

Embodiment Construction

[0022] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0023] The present invention is described in detail below by intercepting an image containing a human body from a TV screen, but the present invention is not limited to the field of television, and may involve electronic consumer products such as digital photo frames and displays. In an embodiment, the image with the head portrait of the front human body cut from the TV is used as the image to be detected, so that the skin color region of the human body is mainly the face region; The method of the present invention is also applicable to the skin color detection of images of multiple human bodies and exposed most of the skin of the human body.

Abstract

The invention relates to an assessment method of human body complexion, comprising the following steps: putting an image to be assessed in a first color space; carrying out the first assessment on the image to be assessed in the first color space; carrying out the second assessment on the result of the first assessment in the second space; determining the human body complexion area according to the result of the second assessment; extracting the color characteristics of the human body complexion area; and carrying out assessment on the human body complexion according to the color characteristics. The invention carries out assessment on the picture quality of a TV through the assessment of the human body complexion so as to realize the automatic detection of the human body complexion in the image or in the TV pictures.

Description

technical field [0001] The invention relates to a method for evaluating human skin color, in particular to a method for extracting human skin color features in images or pictures and evaluating the corresponding skin color, which can be applied to the evaluation of television image quality accordingly. Background technique [0002] Skin color detection has been widely used in face detection, gesture recognition, human tracking, sensitive image filtering and other problems. It is usually used as a preprocessing link to reduce the computational complexity of problem solving. Due to the influence of race, illumination, background and other factors, it is still a challenging problem to accurately segment human skin color regions. [0003] At present, the commonly used skin color detection algorithms can be roughly divided into four categories: simply defined skin color model, non-parametric skin color model, parametric skin color model, and dynamic skin color model. The simple...
