不需要彩色空间转换的人脸肤色的自动白平衡方法

Efficient automatic white balance techniques of face-color for bypassing color coordinate transformations

在多数彩色图像处理的第一步是将RGB空间转换到其他彩色空间,如YCrCb,HIS,YIQ等,然后再进行处理。然而这种变换需要大量的内存空间和计算时间。提出了一种不需要进行彩色空间转换,就可以实现的人脸自动白平衡方法。实验表明此算法效果很好。

The first step in many applications of color image processing is the transformation of the image data from RGB space to other color space such as YCrCb,HIS,YIQ etc. Unfortunately,this process requires large amounts of memory and computation,especially for large image. A new algorithm for bypassing the costly coordinate transformations when white balance can be performed automatically on a digit image which contains a human face was presented. Experiment results showed its high efficient performance.
