YUV and YIQ are two color spaces often used in image processing.

YUV和YIQ是在图像处理研究领域经常用到的两种颜色空间。

We can increase the division effect by the saturation information in YIQ space because human face has much yellow weight.

由于人脸肤色包含了较多的黄色分量，我们可以在YIQ空间利用彩色的饱和度信息来增强分割效果。

Chroma space model adopts traits in skin color of YUV and YIQ color spaces.

色度空间模型是采用YUV和YIQ两种颜色空间在肤色方面的特性来进行肤色检测的.

Here a watermarking scheme for color image authentication is proposed, which operates in the wavelet domain. Firstly, the color image is transformed from the model of RGB to that of YIQ;
