如何在matlab中从nifti图像中逐片写入？

Question

我通过使用matlab工具箱读取nifti图像，但我们如何逐片写入另一种格式，如.jpg或png？我试着这样：

V=niftiread('Brats17_2013_2_1_flair.nii.gz');
imshow(V(:,:,1),[]);
imwrite(V,'test.jpg')
Error using imwrite (line 442)
Cannot write signed integer data to a JPEG file.
imwrite((V(:,:,1),[]),'test.jpg');
imwrite((V(:,:,1),[]),'test.jpg');

Error: Expression or statement is incorrect--possibly unbalanced (, {, or [.

Answer 1

只需通过“saveas”命令保存图片。它工作正常。

h = imshow(V(:,:,1),[]);
saveas (h,'test.jpg');

祝好运
