摘要: 肤色侦测被用于许多的影像处理技术,像是脸部侦测或是姿势侦测等等。由于肤色会随着不同光源环境以及不同种族而有所变化,造成使用肤色侦测准确性会降低,因此有许多利用前处理像是曝光修正、白平衡或是肤色再侦测等等的技术用来提高侦测效果,然而自动化的调整结果不一定理想,原因在于推测正确颜色需要够多的资讯,而自动化调整无法得到哪些是正确的讯息。
本篇论文为了避免受到光源影响采用非色彩部份的资讯来辅助侦测。主要方法是用颜色作为肤色侦测的基础,亮度作为去除非肤色的部份的方法,加上使用脸部侦测用来寻找脸部位置。将辨认出真正人脸的颜色取出,利用脸部的颜色来推断出整体的肤色,进而提高侦测率。实验结果将针对各个种族分析使用亮度的优缺点以及有脸部侦测的差别性和色彩修正的差别性。
Skin detection was used in many image processing technologies, such as face detection or gesture recognition and so on. Due to the skin color will be changed by in different light environments and in different races, the skin detection rate will be decreased, so there are many technologies to increase the efficient, such as preprocessing which is like white balance, color correction and etc. , or adaptive skin detection. However, automatic adjusted results may not be correct. The reason is that the correct color needs enough information. The adjustment can not be automated which is the right information.
In this paper, in order to avoid the effects of light, uses achromatic feature to increase the skin detection rate. The main method is used color to be the basis, luminance as a way to remove noise, coupled with using face detection to find the location of face. Identifying the true human face color, and uses the face color information to detect skin, it will improve skin detection rates. The experimental results will be used for analysis of all races as well as the advantages and disadvantages of brightness and to detect the difference between the face and color differences of the amendment.
