我试图从另一个图像中减去一个图像, 有点像这个:
Image<Gray, float> result, secondImage;
Image<Gray, byte> firstImage;
result = firstImage - secondImage;
但它犯了一个错误
Operator - cannot be applied to operands of type Emgu.CV.Image<Emgu.CV.Structure.Gray,byte> and Emgu.CV.Image<Emgu.CV.Structure.Gray,float>
也许我需要将第一个图像转换为 Imaage< gray, floor> 类型。 但我不知道该如何操作 。
<强度 > 彩色和深度转换
在不同颜色和深度之间转换图像是简单的。例如,如果您有图像 Ing1 并且想要将其转换成灰度的 Single 灰度图像,您需要做的就是
Image<Gray, Single> img2 = img1.Convert<Gray, Single>();
所以,在你的情况中,你可以使用
result = firstImage.Convert<Gray, float>() - secondImage;
