把hdf5文件转换为灰度

Question

如何在Julia中将.h5文件转换为灰度？

我试过这个

MATCH (n) 
WHERE any(x IN n.fruits WHERE x IN ['orange', 'grape', 'apple'])
RETURN n;

我收到此错误：

img = stack[:,:,100] #just some hdf5 file
img = convert(Image{Images.Gray}, img)

Answer 1

我猜你也是using定义Image的其他一些软件包，这与Images.jl中的定义有冲突。让我们假设其他包名为PythonImage。试试这样：

using Colors   # that way you don't have to say `Images.Gray`
import PythonImage, Images  # `import` rather than `using` prevents conflicts

imgg = convert(Images.Image{Gray}, img)

# ...if you need the other one, use `PythonImage.Image`

或者您可以using Images和import PythonImage（反之亦然）。对于他们两个人来说，唯一不能做的就是using，并希望一切顺利。
