摘要: | 在本文中,我们提出一套偏好肤色修正系统,能够针对使用者的需要,对肤色做出适当调整。它利用了类神经网路来实现肤色侦测,不但准确而且快速。并且根据我们所设计的偏好肤色实验,能够定义出使用者对于不同光源状况下所偏好的肤色。另一方面,我们也提出了一套利用模糊归属函数来根据影像亮度对肤色做分类的方法,应用在偏好肤色修正系统中。根据实验结果,我们可以发现此系统对于不同人种的肤色侦测效果都很准确,而且在肤色调整的时候也不会产生瑕疵。 In this thesis, we propose a system of preferred skin color reproduction, which can adjust the skin color based on users’ preference. There are three main function blocks in this system: skin color detection, preferred skin color definition, and skin color correction. First, we adopt neural network to detect skin color in an efficient way. A fuzzy logic method is proposed to classify the detected skin color. Second, users’ preferred skin color on different lightness is defined through a deliberate experiment. Based on the conclusion of the experiment, the proposed system can properly modify the detected skin color to achieve users’ preference without producing boundary artifacts. |
