| 摘 要： | 对彩色数字图像进行降噪处理时，为兼顾标量处理法的简便性和矢量处理法的有效性，提出一种对彩色空间域实行替换的方法。采用均值滤波法在RGB域内进行滤波处理，将图像数据从RGB域转换到HSI域，用滤波处理后的H域、S域替换含有噪声的H域、 S域。对由双目内窥镜采集的实际彩色图像进行实验，结果证明该域替换法可以结合标量处理和矢量处理的优点，达到比一般标量处理法及简单矢量处理法更好的降噪效果。

| Abstract: | Considering the simplicity of scalar processing and the effectiveness of vector processing when doing color digital image noise reduction,a method of domain replacement is proposed in this paper.It processes the image data in RGB space with mean filtering,converts the image data from RGB to HSI,and replaces the original H and S domain with that filtered.The noise in H and S domain is reduced indirectly after these operations.The method is tested with an actual color image captured from a binocular endoscope... |
