writing a image to a folder via imwrite in Matlab

Question

I try to write a image to a folder but imwrite has no input for specifying a folder name. Is there any other func. or way to store image to a folder. Maybe I amiss on imwrite if I do, I am sorry about it.

When I use a file name parameter like "folder1/folder2/img.jpg" it does not create folders accordingly and it just create a file named as "folder1/folder2/img.jpg"

I also try to use mkdir ahead in time but it also gives "Permission Denied" on console.

By the way I am using Linux. May be about permission problem?

Answer 1

The filename parameter doesn't mean just the name - you can give it a path, either absolute or relative, as part of the string.

imwrite(img,'my/folder/images/file','jpg')

for example.

Answer 2

The folder would just be specified in the file name, like this

imwrite(img, 'folder1/filename.tif','tif');

or if you want to use an absolute path.

imwrite(img, 'C:/Users/UserName/folder1/filename.tif','tif');

Check out wikipedia on absolute and relative paths.
